But then ALL types are accepted!

I just want to accept vars of types that comply with concept C

Why must we do this:

// concept C
template <C ...T >
decltype(auto) func (T ...args)
          return args + ...;

So unnecessary!

Why not:

decltype(auto) func (C ...args)
          Return args + ...;


Not hard to implement, as auto in param list is already implemented.
This would help lots, & would speed up coding, making it more maintainable too!
