`until` does not iterate, it simply returns a range which ends
when your condition is satisfied.

[ . . X . . . . . . . . ]
I want:
[ . . X ]
Isn't this what `until` does?
countUntil + take can kind of mitigate the problem, but that
warps the type system: The type of take is not the type of the
range.
I believe wrapper ranges like `take` return ranges with the same
capabilities as the ranges they wrap. This modularity design
assumes that you will use the result in functions that accept
ranges, i.e. templated functions that expect that the types of
their parameters satisfy the is*Range constraints.
To avoid misunderstanding or miscommunication, could you post the
practical problem you encountered, with context?
