Raymond Hettinger  added the comment:

+1 I think this change will be essential.  IIRC, elsewhere Guido approved a 3.7 
change so that the ABC will no longer be visible in collections.

[issue30143] Using collections ABC from collections.abc rather than collections in 2to3 converted code

2017-04-23 Thread Serhiy Storchaka 

New submission from Serhiy Storchaka:

Proposed patch makes 2to3 generating a code that uses abstract collection 
classes Sequence and Mapping from collections.abc rather than collections. 
Since abstract collection classes now are defined in collections.abc and 
collections contains only aliases for compatibility, this is more idiomatic 
Python 3 code.
