Suggested amendment to PEP 255 (fwd)

[Dr. David Mertz]

One more non-vote for a new spelling of "generator."  Despite
protestations to the contrary by the timbot, I see the very subtle and
late-in-the-definition-body use of 'yield' as a train wreck waiting to
happen.  Never mind newbies, I am certain that *I* would stumble over
the difference between generators and (real) functions all the time.

As spelling goes, I like:

  generator foo(args):

the best.  But the other suggestions below are sufficiently good also.

Yours, David...

Im 100% with this too. doubleplusgood would be my vote, if I had one.
Generators do seem different enough from functions to warrant a different syntax.

some other syntax possibilities:

gen foo(args):
   yield x

def foo(args) generator:
   yield x

def foo(args) as generator:
   yield x

def generator foo(args):
   yield x
