That's not a problem. We could introduce a rule that when the with block
is part of an assignment, the with block runs in a seperate scope.
A bigger problem is that this would be the first statement which
returns a value (as opposed to having an effect via side-effects, like
the class and def statements), and it would only be usable in
assignments:
spam = with eggs() as cheese:
...
but not:
items = [x, y, with eggs() as cheese: ... , z]
