--- Comment #5 from ZombineDev <petar.p.kirov at gmail.com> ---
I guess the trickiest problem to solve is what to do about is(typeof({ code;
})) and __traits(compiles, { code; }). Allowing those constructs to yield true
while containing non-betterc code would lead to logical contradictions.
Disallowing betterc code in such speculative contexts, while allowing it in
CTFE context would be strange.
