[issue40334] PEP 617: new PEG-based parser

STINNER Victor added the comment: Once PR 19503 will be merged, I would be interested to see if setjmp()/longjmp() can be avoided. I'm scared by these functions: they require that all functions in between setjmp() and longjmp() call stack have no state and don't need any cleanup at exit.

[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
