Hello everybody,

open(fname2) as f2,
open(fname3) as f3,
open(fname4) as f4

Is there a reason that brackets are not allowed in this place?
The syntax (slightly simplified) is:
"with" expression ["as" name] ":"
but the expression itself can start with a parenthesis, so if it saw a
parenthesis after the "with" it would be ambiguous.
For example, compare:
with (open(fname1) as f1, open(fname2) as f2):
with:
with (open(fname1)) as f1, open(fname2) as f2:
