One is a language change like &&.  If we had

 template<class T>
 void sort(T t) {}

 template<class T>
 void sort(T& t) {}

template< class T >
void sort( const T& t )

wouldn't it be possible to enable/disable certain combination in certain
situaltions, so it
would just work ? Anyway, my brain has stopped thinking, so I'll better do
some homework.
