Code from forum post [1]

```d.d
class R {
}

void foo (R r)
{
}

alias fn = void function (R);

void lyr (fn F) (R r)
{
}

immutable fn foo_ptr = &foo; // line 14
pragma (msg, typeof (foo_ptr));

auto ptr = lyr!(foo_ptr);    // line 17
```

$ dmd -c d.d
immutable(void function(R))
d.d(14): Error: expression `& foo` is not a valid template value argument

expected: Error reported for line number 17.
