+
+    Good for when you need to test for membership (`a in set`),
+    but the set should not grow unbounded.
+
+    ``maxlen`` is enforced at all times, so if the limit is reached
+    we'll also remove non-expired items.
+
+    You can also configure ``minlen``: this is the minimal residual size
+    of the set.
+
+    All arguments are optional, and no limits are enabled by default.
+
+    Arguments:
+        maxlen (int): Optional max number of items.
+            Adding more items than ``maxlen`` will result in immediate
+            removal of items sorted by oldest insertion time.
+
+        expires (float): TTL for all items.
+            Expired items are purged as keys are inserted.
+
+        minlen (int): Minimal residual size of this set.
+            .. versionadded:: 4.0
+
+            Value must be less than ``maxlen`` if both are configured.
+
+            Older expired items will be deleted, only after the set
+            exceeds ``minlen`` number of items.
+
+        data (Sequence): Initial data to initialize set with.
+            Can be an iterable of ``(key, value)`` pairs,
+            a dict (``{key: insertion_time}``), or another instance
+            of :class:`LimitedSet`.
+
+    Example:
+        >>> s = LimitedSet(maxlen=50000, expires=3600, minlen=4000)
+        >>> for i in range(60000):
+        ...     s.add(i)

+        >>> '10' in s  # '10' did expire and was purged from set.
+        False
+        >>> len(s)  # maxlen is reached
+        50000
+        >>> s.purge(now=time.monotonic() + 7200)  # clock + 2 hours
