It's just a generator, and will be terminated early if possible.

I'm pretty sure adding a key function to any and all has already been
submitted several times, and from what I remember it was struck down
every time because the use case is covered by Laurens's suggestion: key
functions are necessary when you'd otherwise need DSU (because the
result is the original input, not the key function's output) but it's
not the case for any() and all()
