The following is strictly IMHO:
I dont think such an ugly hack will ever make it into python.

If you need to change a varibale from a higher scope, you most likely have a
serious design flaw in your program. At the moment i can think of no
situation where this would be needed. And if there really is such a case you
can allways define the variable global.

just my 2 eurocents
