I like maybe_value dereferences NULL with SIGILL and you have at least a backtrace with exact invalid access position.

  Oh, you can get the information at compile time as well. https://godbolt.org/z/hTYbTE8j8 https://godbolt.org/z/hTYbTE8j8 (or https://godbolt.org/z/K1M68sY3Y https://godbolt.org/z/K1M68sY3Y but this will be tricky in a larger code base)

    That's the reason language/compiler should directly support optionality. You can't fool yourself and have to handle all cases: https://godbolt.org/z/4GqMdPej3 https://godbolt.org/z/4GqMdPej3

      So it seems exactly the same to me?

        Nice one. gcc/clang are smart enough to get .ok condition statically. I'm very curios how complex an expression could be.
