3.2 and above provide contextlib.ExitStack, which I just now
learned about.

with contextlib.ExitStack() as stack:
    _in = stack.enter_context(open('some_file'))
    _out = stack.enter_context(open('another_file', 'w'))

It ain't beautiful, but it unfolds the nesting and gets rid of
the with statement's line-wrap problems.
