Bug 14669 – auto attribute on function parameter should be error always

Test case: void foo1()(auto int a) {} // line 1 void foo2()(auto int a) {} void main() { alias f1 = foo1!(); // line 6 foo2(1); // no error!? } Output: test.d(1): Error: auto can only be used for template function parameters test.d(6): Error: template instance test.foo1!() error instantiating The explicit instantiation foo1!() correctly rejects the invalid function parameter `auto int a`, but the second IFTI call foo2(1) does not report same error. This is not related to `auto ref`.
