If I understand the OP, the issue is that the 'with' creates a name
binding and an indentation level for no purpose; it's like doing this:

f = open(path)
for line in f:
    ...

In that instance, it's possible to inline the function call and use
its result directly; it would be nice to be able to do the same with a
context manager. However, since 'with' isn't an expression, it's not
possible to directly inline the two.

I think the utility function iterwith() is a good - and probably the
best - method; it demands nothing special from the language, and works
quite happily.
