Not to defend Paul's proposal, which I, like many others on this list, still 
find counterintuitive and a break with the current syntax/semantics of Python, 
but I don't think it's fair to say that his proposal will change much 
currently legal code.  Grep the Python source for functions with __*__ local 
variable assignments and tell me how many you find.  I wasn't able to find 
any, though perhaps my skills with grep are not up to par...  For that matter, 
grep any Python source for functions like this.  I'd bet you find the same.

Certainly, Paul's proposal would change what code is legal, but I don't think 
it would actually make much current Python code illegal -- no one codes like 
this!  Which is probably why it seems so counterintuitive to me...
