[issue20784] 'collections.abc' is no longer defined when collections is imported

[R. David Murray]

R. David Murray added the comment:

It is a backward compatibility bug.  Something that used to work doesn't any more.  And it was explicitly *made* to work previously (the original __init__ statement was 'import collections.abc').  And it is is an implementation bug in the original patch because otherwise there would be no point in importing _collections_abc in __init__.

But you are right, it is relatively unlikely that anyone is relying on it.
