Are you re-thinking the restriction to LL(1) grammars?

Indeed. I think it served us well for the first 10-15 years, but now it is just a burden.

See a thread I started at Discourse:
https://discuss.python.org/t/switch-pythons-parsing-tech-to-something-more-powerful-than-ll-1/379

And some followup there:
https://discuss.python.org/t/preparing-for-new-python-parsing/1550

Note that this is very much speculative.
