[pypy-dev] plans for the peg parser in pypy 3.9

[Omer Katz]

Kudos on the great work!

I honestly don't think there's a need to keep the old parser around if
CPython already proved that the new one works just fine.
I think we're allowed to be less conservative here because of that.

We can always revert your patch if something goes wrong.
