No backstory that I'm aware of -- only something that doesn't really
fall out from the generators design. There's just no sensible name you
could give the value (without getting "creative" with lexical scope),
and no continuation waiting to receive it.
Right. Anyone know whether this has come up as a PEP or suggestion on
python-dev?
The meeting notes Kevin cited in the thread root don't mention it, but
IIRC we did briefly talk about syntax that could be added in a future
edition (AKA next year in a spec, next month in a browser
implementation) for receiving that first-next value:
function* gen(a, b, c) first {
...
}
Not bikeshedding, some found it ugly or too terse, many wondered about
other future syntax vying to go after the parameter list. But the idea
seems good.
