Guido, do you think there is some way to decouple collections.abc from spilling into the namespace for non-abc collections module?

At the interactive prompt, running dir() on collections gives an alphabetical hodgepodge of the two modules.  To my eyes, it is difficult to discern the concrete from the abstract.

>>> dir(collections)
