Subject: Re: Ideas on debug constexpr functions or other functions that have been 100% removed from the EXE

This could be tricky given that constexpr's aren't compile-time
guaranteed, hence there would be a necessary debug mechanism to
distinguish between constexpr's which are in fact being compile-time
evaluated and those which aren't. Which would be useful anyway, in my
opinion. I don't use them so am not sure whether any compiler ash that
feature.
