Agreed, though Jan made some good points about this.  But my concern
with the decorator approach is that it isn't visually distinct enough
from normal decorators.  The @(...) form does help though.

How about another approach:

   given:
       lock=threading.RLock())
   def my_foo():
       with lock:
           "do foo"

or

   def my_foo():
       with lock:
           "do foo"
   given:
       lock=threading.RLock())

It's an idea that just popped into my head (*cough* PEP 3150 *cough*).
 But seriously, I don't think statement local namespaces have come up
at all in this super-mega thread, which surprises me (or I simply
missed it).  Doesn't it need a "killer app".  Maybe this isn't
"killer" enough, but it's something! :)
