I'm confused by the section on "no alternate binding operator" in PEP 3099. On the one hand, it says no alternative binding operator will be considered; yet the link provided shows that Guido is in favor of developing a syntax for non-local assignment. Please excuse me if this post violates that rule. Here's my suggestion on what the syntax should look like:
set! var val Scheme users will recognize this syntax, which has the distinct advantage of not being confusable with regular assignment; whereas, this is an unfortunate feature of :=, which Guido has already rejected. The way this is supposed to work is you go to the inner-most scope in which var is declared and change its value there to val. If var does not occur in any containing scope, you could raise an UndeclaredVariable exception. Thoughts?
