Since the parser module is documented as deprecated since Python 2.5 and a new parsing technology is planned for 3.9, the parser module is scheduled for removal in 3.9.
Hm interesting comment. Does anybody know what the new approach to parsing Python in 3.9 is ? I searched python-dev@ but couldn't find any references to it.
I found an interesting tidbit about Rust "switching" from LL to LR here:

And I noticed some rules in Python's grammar that are awkward in LL parsing (set and dict literals, and comprehensions).
I wonder if those things motivated the switch? They certainly work though.
