Yes, consensus clearly converged on the proposed syntax (the mention
of "generators" in the construct's name was the part that I think prompted
the desire for 'yield' -- had they been called "iterator expressions" I
suspect nobody would have missed 'yield' even transiently:-).

Yes, fair summary.  The one persistent (but low-as-a-whisper) grumbling
is by one A.M., who keeps mumbling "they're _iterator_ expressions, the
fact that they use generators is an implementation detail, grmbl grmbl":-).
But then, he IS one of those pesky must-always-have-SOME-whine types.
