and probably always will.

It's horrible syntax (no surprise), and being a templated 
function means it's recompiled N times... but there's at least 
something for it now.

There is array_view and string_view that have been proposed (and 
I even think  accepted) for C++17.

But if you want a fat pointer, you can just write one yourself:

template< typename T >
struct FatPtr
{
   template< std::size_t N >
   FatPtr( T (&a)[N] )
      : p (a)
      , n (N)
   { }

   T *p;
   std::size_t n;
};

void function( FatPtr<char> a );

int main( )
{
   char a[128];
   function(a);

   function("foo");
}
