The following code fails:
----------
void foo(int x, T...)(T args)
{
    pragma(msg, T);
}

void main()
{
    foo!(42)(1, 2, 3);
}
----------

with 
-----
()
/d451/f334.d(8): Error: function f334.foo!(42).foo (() args) does not match
parameter types (int,int,int)
/d451/f334.d(8): Error: expected 0 arguments, not 3 for non-variadic function
type void(() args)
