Sorry, I didn't understand. Didn't mean to imply it couldn't be used everywhere.

My expectations:
with open(fn) as f: # current behavior
with (open(fn) as f): # syntax error, missing clause
with closing(urlopen(url)) as dl: # current behavior
with closing(urlopen(url) as dl): # syntax error, missing clause
with (closing(urlopen(url)) as dl): # syntax error, missing clause
In other words, the with statement would continue to require an as clause
outside of the parentheses. A double name binding doesn't seem very useful however.
