> But this is the format currently used by typed_ast. I think it would just cause a cascade of annoying failures for tools that switch between typed_ast and the 3.8 version of ast. Such as mypy.
typed_ast is a 3rd party project. But here we are talking about Python stdlib. If a project moves from typed_ast to stdlib ast, IMHO it should be quite easy to replace 4 with (3, 4), especially if 4 raises an error, no?
IMHO it's a good opportunity to fix it.
I would prefer to not have to batch many backward incompatible changes into Python 4... |
