The spec does not seem to require that tuple parameters are the last parameter
in the list, but this doesn't work:

void foo(U...)(int t, U u) { }
void bar(U...)(U u, int t) { }

void main()
{
  foo(1, 2, 3);  // Ok, IFTI works
  bar(1, 2, 3);  // error: cannot deduce template function from argument types
(int,int,int)
  bar!(int, int)(1, 2, 3);  // Ok.
}
