+    Nodes that were part of a collection of statements (that applies to

+class Template:
+    r"""Represents a compiled template.
+
+    :class:`.Template` includes a reference to the original
+    template source (via the :attr:`.source` attribute)
+    as well as the source code of the
+    generated Python module (i.e. the :attr:`.code` attribute),
+    as well as a reference to an actual Python module.
+
+    :class:`.Template` is constructed using either a literal string
+    representing the template text, or a filename representing a filesystem
+    path to a source file.
+
+    :param text: textual template source.  This argument is mutually
+     exclusive versus the ``filename`` parameter.
+
+    :param filename: filename of the source template.  This argument is
+     mutually exclusive versus the ``text`` parameter.
+
+    :param buffer_filters: string list of filters to be applied
+     to the output of ``%def``\ s which are buffered, cached, or otherwise
+     filtered, after all filters
+     defined with the ``%def`` itself have been applied. Allows the
+     creation of default expression filters that let the output
+     of return-valued ``%def``\ s "opt out" of that filtering via
+     passing special attributes or objects.
+
+    :param cache_args: Dictionary of cache configuration arguments that
+     will be passed to the :class:`.CacheImpl`.   See :ref:`caching_toplevel`.
+
+    :param cache_dir:
+
+     .. deprecated:: 0.6
+        Use the ``'dir'`` argument in the ``cache_args`` dictionary.
+        See :ref:`caching_toplevel`.
+
+    :param cache_enabled: Boolean flag which enables caching of this
+     template.  See :ref:`caching_toplevel`.
+
+    :param cache_impl: String name of a :class:`.CacheImpl` caching
+     implementation to use.   Defaults to ``'beaker'``.
+
+    :param cache_type:
+
+     .. deprecated:: 0.6
+        Use the ``'type'`` argument in the ``cache_args`` dictionary.
+        See :ref:`caching_toplevel`.
+
+    :param cache_url:
+
+     .. deprecated:: 0.6
+        Use the ``'url'`` argument in the ``cache_args`` dictionary.
+        See :ref:`caching_toplevel`.
+
+    :param default_filters: List of string filter names that will
+     be applied to all expressions.  See :ref:`filtering_default_filters`.
+
+    :param enable_loop: When ``True``, enable the ``loop`` context variable.
+     This can be set to ``False`` to support templates that may
+     be making usage of the name "``loop``".   Individual templates can
+     re-enable the "loop" context by placing the directive
+     ``enable_loop="True"`` inside the ``<%page>`` tag -- see
+     :ref:`migrating_loop`.
+
+    :param encoding_errors: Error parameter passed to ``encode()`` when
+     string encoding is performed. See :ref:`usage_unicode`.
+
+    :param error_handler: Python callable which is called whenever
+     compile or runtime exceptions occur. The callable is passed
+     the current context as well as the exception. If the
+     callable returns ``True``, the exception is considered to
+     be handled, else it is re-raised after the function
+     completes. Is used to provide custom error-rendering
+     functions.
+
+     .. seealso::
+
+        :paramref:`.Template.include_error_handler` - include-specific
+        error handler function
+
+    :param format_exceptions: if ``True``, exceptions which occur during
+     the render phase of this template will be caught and
+     formatted into an HTML error page, which then becomes the
+     rendered result of the :meth:`.render` call. Otherwise,
+     runtime exceptions are propagated outwards.
+
+    :param imports: String list of Python statements, typically individual
+     "import" lines, which will be placed into the module level
+     preamble of all generated Python modules. See the example
+     in :ref:`filtering_default_filters`.
+
+    :param future_imports: String list of names to import from `__future__`.
+     These will be concatenated into a comma-separated string and inserted
+     into the beginning of the template, e.g. ``futures_imports=['FOO',
+     'BAR']`` results in ``from __future__ import FOO, BAR``.
+
+    :param include_error_handler: An error handler that runs when this template
+     is included within another one via the ``<%include>`` tag, and raises an
+     error.  Compare to the :paramref:`.Template.error_handler` option.
+
+     .. versionadded:: 1.0.6
+
+     .. seealso::
+
+        :paramref:`.Template.error_handler` - top-level error handler function
+
+    :param input_encoding: Encoding of the template's source code.  Can
+     be used in lieu of the coding comment. See
+     :ref:`usage_unicode` as well as :ref:`unicode_toplevel` for
+     details on source encoding.
+
+    :param lookup: a :class:`.TemplateLookup` instance that will be used
+     for all file lookups via the ``<%namespace>``,
+     ``<%include>``, and ``<%inherit>`` tags. See
+     :ref:`usage_templatelookup`.
+
+    :param module_directory: Filesystem location where generated
+     Python module files will be placed.
+
+    :param module_filename: Overrides the filename of the generated
+     Python module file. For advanced usage only.
+
+    :param module_writer: A callable which overrides how the Python
+     module is written entirely.  The callable is passed the
+     encoded source content of the module and the destination
+     path to be written to.   The default behavior of module writing
+     uses a tempfile in conjunction with a file move in order
+     to make the operation atomic.   So a user-defined module
+     writing function that mimics the default behavior would be:
+
+     .. sourcecode:: python
+
+         import tempfile
+         import os
+         import shutil
+
+         def module_writer(source, outputpath):
+             (dest, name) = \\
+                 tempfile.mkstemp(
+                     dir=os.path.dirname(outputpath)
+                 )
+
+             os.write(dest, source)
+             os.close(dest)
+             shutil.move(name, outputpath)
+
+         from mako.template import Template
+         mytemplate = Template(
+                         filename="index.html",
+                         module_directory="/path/to/modules",
+                         module_writer=module_writer
+                     )
+
+     The function is provided for unusual configurations where
+     certain platform-specific permissions or other special
+     steps are needed.
+
+    :param output_encoding: The encoding to use when :meth:`.render`
+     is called.
+     See :ref:`usage_unicode` as well as :ref:`unicode_toplevel`.
+
+    :param preprocessor: Python callable which will be passed
+     the full template source before it is parsed. The return
+     result of the callable will be used as the template source
+     code.
+
+    :param lexer_cls: A :class:`.Lexer` class used to parse
+     the template.   The :class:`.Lexer` class is used by
+     default.
+
+     .. versionadded:: 0.7.4
+
+    :param strict_undefined: Replaces the automatic usage of
+     ``UNDEFINED`` for any undeclared variables not located in
+     the :class:`.Context` with an immediate raise of
+     ``NameError``. The advantage is immediate reporting of
+     missing variables which include the name.
+
+     .. versionadded:: 0.3.6
+
+    :param uri: string URI or other identifier for this template.
+     If not provided, the ``uri`` is generated from the filesystem
+     path, or from the in-memory identity of a non-file-based
+     template. The primary usage of the ``uri`` is to provide a key
+     within :class:`.TemplateLookup`, as well as to generate the
+     file path of the generated Python module file, if
+     ``module_directory`` is specified.
