Reduced test case.
------
void bug1390a(A,U)(void delegate(U,A) dg, A arg)
{}
void bug1390(A,U...)(void delegate(U,A) dg, A arg)
{}

struct FooStruct   {
      void foo(uint i,char c) {}
}

void bar1390() {
    auto temp = new FooStruct;

    bug1390a!(char,uint)(&temp.foo, 'c');
    bug1390a            (&temp.foo, 'c');

    bug1390!(char,uint)(&temp.foo, 'c');
    bug1390            (&temp.foo, 'c');
}
----
The '1390a' cases work, but on D1, the second '1390' fails. On D2 *both* of the
'1390' instantiations fail.
