? No :)

What I meant is: If I have `constexpr const char* f = "ccc"` and sizeof(f) is pointer size, I imagine there to be a pointer somewhere that points to a constant string literal in the constant segment. But if it is a real pointer, it would have to be set after program load, since only then you know the address of the string literal.

Idk. Did not investigate deeply. I like the ability of build time stringlen via sizeof for constexpr char[], that's why I prefer it.
