I thought so too, but in my tests given:

  template<unsigned N>
  void foo(const char (&S)[N]) { }
  
  void foo(const char *S) { }

I could never get the compiler to invoke the first one, no matter what I passed in.  It's possible I was missing some subtlety though, I'll just try it with Mehdi's forthcoming patch and see what I get.
