Quoting the spec:
"In order to be executed at compile time, the function must appear in a context
where it must be so executed"
Note the word MUST. I don't see anything in the spec to indicate that it is
optional. It's pretty simple actually -- if the compiler *needs* a constant,
and it sees an expression, it attempts to constant-fold that expression. If the
expression contains a function call, CTFE will be used. CTFE is not used in any
other context - it never happens unless requested.
> Other writing I've seen suggests that CTFE is an optimization, not a language
requirement.
Can you remember where you saw that writing, or got that impression? If it's
anywhere public, we need to get rid of it, since it is not correct.
