with-statements have a syntactic quirk, which I think would be useful to fix.
This is true in Python 2.7 through 3.3, but it's likely not fixable until 3.4,
unless of course it's a bug <wink>.
Legal:
>>> with open('/etc/passwd') as p1, open('/etc/passwd') as p2: pass
Not legal:
>>> with (open('/etc/passwd') as p1, open('/etc/passwd') as p2): pass
Why is this useful? If you need to wrap this onto multiple lines, say to fit
it within line length limits. IWBNI you could write it like this:
with (open('/etc/passwd') as p1,
open('/etc/passwd') as p2):
pass
This seems analogous to using parens to wrap long if-statements, but maybe
there's some subtle corner of the grammar that makes this problematic (like
'with' treating the whole thing as a single context manager).
Of course, you can wrap with backslashes, but ick!
