Then clamp should be
template<class T> T clamp( T const & value, typename identity<T>::type const & low, typename identity<T>::type const & high );
I second this. BTW, The return type could be T const&.
Okay, I'll bite. Why identity and not just T?
(I thought this might be a joke at first.)
Using identity means that T is deduced solely based on the first argument. In Christ, Steven Watanabe
