Here\'s a largely academic exercise in understanding conversion operators, templates and template specializations.The conversion operator template in the following code works for int, float, and doubl

I used to think that metaprogramming involved modifying the program, and (as do some answers to What is reflection and why is it useful? ) that reflection merely consisted of introspection of a progra
