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

[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.
