Ideally there should be an intrinsic for until 😞

[elect]

what is it an intrisic exactly?

[damian]

It's a special case in the compiler that implements a particular construct differently than can be done in the language itself (if it can be done at all). In the case of using for (i in n..m), for example, the compiler knows that it can output a "primitive" loop instead of doing the whole `IntRange`/`Iterator` dance.
