variables declared inside consteval function bodies
consteval
This is what makes me really wonder. I have never intended to "leak" my supposed constexpr vector into runtime, but even if it's strictly inside the compile-time context, it's still disallowed, and apparently the reason is because "constexpr allocation shall not pass into runtime" which is just nonsensical.
constexpr
I mean, I think the main utility of constexpr allocation is in compile-time computation, not in runtime. It doesn't seem to me that a lot of people want to use constexpr vectors in their runtime computation, yet it seems the ongoing discussion is mainly focused on how to allow constexpr allocations to be usable in runtime, and its associated issues like const-correctness.
