+@itemize
+@item
+RangeMap: A mapping that accepts a range of values for keys.
+@item
+Projection: A subset over an existing mapping.
+@item
+KeyTransformingDict: Generalized mapping with keys transformed by a function.
+@item
+FoldedCaseKeyedDict: A dict whose string keys are case-insensitive.
+@item
+BijectiveMap: A map where keys map to values and values back to their keys.
+@item
+ItemsAsAttributes: A mapping mix-in exposing items as attributes.
+@item
+IdentityOverrideMap: A map whose keys map by default to themselves unless overridden.
+@item
+FrozenDict: A hashable, immutable map.
+@item
+Enumeration: An object whose keys are enumerated.
+@item
+Everything: A container that contains all things.
+@item
+Least, Greatest: Objects that are always less than or greater than any other.
+@item
+pop_all: Return all items from the mutable sequence and remove them from that sequence.
+@item
+DictStack: A stack of dicts, great for sharing scopes.
+@item
+WeightedLookup: A specialized RangeMap for selecting an item by weights.
