Heh. Did you see Ray Gibbons's 'Testing Conditions' post before you sent 
this?
I knew if/elif was a much better argument in favour of embedded assignment than 
while loops are.

Anyway, here's the above using my idle thought from that the thread.:
  if m using foo_pattern.search(subject) as m:
    pass
  else:
    pass
And the 'alternative patterns' case:
  if m using foo_pattern.search(subject) as m:
    pass
  elif m using bar_pattern.search(subject) as m:
    pass
  else:
    pass
(Y'know, I'm pretty sure the impetus was regexp matching the *last* time 
embedded assignment came up. . .)

Cheers,
Nick.
