Cleaner perhaps, but not clearer. Instead of seeing the original
function (say, a database retrieve-next call), you see a wrapper and
have to go dig to find out what it's actually doing. Unless it's some
kind of generic handler, like:

def funcinator(func,*args):
   while True:
      var = func(*args)
      if var:
         yield var
      else:
         break

while funcinator(cur.getnext):
    ....

But even that would be problematic until it got so thoroughly
understood that it's like enumerate() - which is itself still not
perfect.
