I meant that following won't compile

   template <typename T> void foo(const T& t) {}

   int main()
   {
     foo(42);
     return 0;
   }

I just tried to compile this and now I see I was wrong about this.  I knew
that

   template <typename T> void foo( T & t) {}

   int main()
   {
     foo(42);
     return 0;
   }

doesn't compile. To me this always made sense since it doesn't make
much sense to take the address of something which is about to disappear
regardless of whether it's "const" or now.  My fix was to use
void foo(T && t) which made sense to me - but of course not available 
until now.

So make a trac ticket and I'll get around to addressing this.
