Nevertheless, it's nice to see how powerful the new parser is!
Any chance this would allow us to have a multi-line with statement?
with self.context_manager_one(some, parameters, that, are, passed) \
as return_value_one, \
self.context_manager_two(self.p, slice(None), None) \
as return_value_two:
but with parentheses instead of backslash continuations?
