The simplest way to do that is to write a unit test that uses a

it pretty much can't know whether a function can be called at
compile time until it tries, but a unit test can catch it if
the function no longer works at compile time.
Not bad, but that is swaying into the cumbersome category. If
that's the best we can do, a @ctfeonly attribute starts looking
pretty good.
