SFINAE: static_assert vs std::enable_if

Question

Are there any disadvantages in the following (suggested!) syntax?

template< typename T >
void f() static_assert(std::is_same< T, int &g         


        

Answer 1

Why would using static_assert be better than the Concepts Lite syntax?

template< typename T >
  void f() requires Int()
  { }

or:

template< Int T >
  void f()
  { }
