[issue36144] Dictionary union. (PEP 584)

Guido van Rossum added the comment: I think for `|=` the only choice is for it to be essentially an alias to `.update()`. So that means `cm |= other` becomes `cm.maps[0].update(other)`. For `|` we are breaking new ground and we could indeed make `cm | other` do something like `ChainMap

[issue36144] Dictionary union. (PEP 584)

Guido van Rossum added the comment: I had just come to a different conclusion. Maybe ChainMap should just not grow `|` and `|=` operators? That way there can be no confusion. `dict() | ChainMap()` and `ChainMap() | dict()` will fail because ChainMap doesn't inherit from dict. (Note th

Guido van Rossum added the comment: OK, that makes sense, it works similar to ChainMap.copy(), which copies maps[0] and keeps links to the rest. So in particular `cm | {}` will do the same thing as cm.copy(). Im not sure if the dict(other) cast is the best way to go about it. Maybe this

[issue40296] help(list[int]) fails

Guido van Rossum added the comment: Yeah, I think help() or pydoc needs to special-case this. (Didn't your other PR attempt to fix this?) Note that issubclass(list[int].__class__, type) returns True -- the __class__ attribute in this case is taken from __origin__, while type() return

[issue40334] PEP 617: new PEG-based parser

New submission from Guido van Rossum : Note: PEP 617 is currently under review by the Steering Council, but if they approve we'd like to get it into alpha 6, and reviews are welcome (even though we're still finagling some corner cases of the implementation). -- messages: 3

[issue40360] Deprecate lib2to3 (and 2to3) for future removal

Guido van Rossum added the comment: I am in favor of this. We could promote LibCST, which is based on Parso, which uses a forked version of pgen2 (the parser in lib2to3). I believe one of these could switch to a fork of pegen as its parser, so it will be able to handle new PEG based syntax
