Since last fall's core sprint in London, Pablo Galindo Salgado,
Lysandros Nikolaou and myself have been working on a new parser for CPython. We are now far enough along that we present a PEP we've written:
Hopefully the PEP speaks for itself. We are hoping for a speedy
resolution so we can land the code we've written before 3.9 beta 1.
Excellent news! One question - will there be any user-visible change as a result of this PEP other than the removal of the "parser" module? From my quick reading of the PEP, I didn't see anything, so I assume the answer is "no".
I suppose it depends on how deep you dig, but the intention is that the returned AST is identical in each case. (We've "cheated" a bit by making a few small changes to the code that produces an AST for the old parser, mostly bugs related to line/column numbers.)
