Hi, 

I like this idea. 

I've put together a short patch that will implement inline
assignment. 

if f() -> name:
  use(name)

or more powerfully:

if f() -> name == 'spam':
   usespam(name)

the old syntax if something as x: is still available if that
is what is desired.

if (f() == 'spam') -> name:
   newname = name.replace('p', 'h') 

Patched against Py3k please kick the tires, I've added some tests and
developed a PEP.
