It's really a compile time check, so you should use static asserts for this.
You should be able to compare using std::is_same and using decltype. You can even use std::static_assert to move the check to compile time. I've seen it happen in libc++ :).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
