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.
