How do you feel about constexpr in C23?

[MarcusJohnson91]

WG14 is considering adding constexpr to C23, they're worried it may kill single pass, no AST compilers from working, and it looks like yours fits that description.

what are your thoughts?

I am unsure, but anything that breaks single pass does make things much more annoying. fwiw, even this compiler is not fully single pass because of tentative definitions, but they don't require too much work at the moment.
