Question: Also, is there any reason not to try and 'constexpr' as many function as you can? As I understand, if the 'constexpr' function cannot be evaluated at compile time, it will just act as a regular function? So best case is you get compile time evaluation wins, worst case is you have a regular acting function.

Optimizing compilers try to do that anyway, afaik? But anyway, for most uses I don't see it having a big effect. Comment...

Question: Hey Justin, do you prefer c-style casts or c++ style casts? The only true benefit of c++ style casts I can see is being able to easily search a codebase for them, validation of casts is cool but maybe not persuasive enough, especially in the case of 'dynamic_cast' which can have runtime penalties.. Cheers :)
