Hello,
Do you think it would be nice to allow with statements inside genexps or
list comprehensions? The functions __enter__ and __exit__ would be
automatically called as iterables are traversed. I am thinking of
drafting a PEP about this. Examples:
I was worried until I twigged that you meant adding a clause rather than
a statement per se. How does this interact with the other clauses in a
comprehension? I'm thinking of monstrosities like:
g = (f.read() for fn in filenames if fn.endswith(".txt") with open(fn)
as f for filenames in get_directory_listing(dir) if .....)
