That looks to me like a perfect argument *in favour* of the
"generator" keyword! I'm a very literal kind of person, and I would
absolutely want "weird things that look almost like functions but
[...] can only be used to make generators" to be clearly labelled
as such without having to hunt through the body of the not-quite-
function.
The signposting needn't even be as in-your-face as a generator
keyword (either instead of or in addition to function): I could get
behind a variation such as:
function f($x, $y) yields {
...
yield $z;
...
}
Or even (stretching a bit to re-use an existing keyword!):
function f($x, $y) return {
...
yield $z;
...
}
Although I like the concept of generators, I would be -1 for any
implementation that doesn't differentiate them in some way from
regular functions.
Cheers!
Mike
