My understanding is that the "0..10" isn't actually a range notation,
and you need to use iota(0, 10). I may be wrong, but if I'm right,
hopefully someone can explain why this syntax works?
I remember there being a discussion about this recently; I'll see if I
can find it.
It works because it's a specialized syntax for foreach. Oh, and I think
in case statements you can use it too, but I don't remember if the first
was inclusive and the second exclusive, or both, or what. But... it just
works for those cases. For the rest you have to use iota...
