    From #91385:

> The compiler error for the most common iota(0, vec.size()) with clang is not great. I was also wondering if instead of raising the error via a failure in the requires clause of the iota_view constructor guideline, it could be maybe raised earlier, e.g., from iota itself, with a nice message.
