If you insert a dot before the recursive factorial call,
it will work correctly.

-----------
template factorial(int n)
{
   static if (n<2) const int factorial = 1;
   else const int factorial = n * factorial!(n-1);
}

template rhino(alias hippo)
{
   const int rhino = hippo!(2);
}

const int lion = rhino!(factorial);
