class documentation

class anon_map(dict):

A map that creates new keys for missing key access.

Produces an incrementing sequence given a series of unique keys.

This is similar to the compiler prefix_anon_map class although simpler.

Inlines the approach taken by sqlalchemy.util.PopulateDict which is otherwise usually used for this type of operation.
