Is it okay to use template parameter instead of **template 
value** parameter?
```d
class R {
}
void foo (R r)
{
}

void lyr (fp_type, R) (fp_type fp, R r)
{
}

pragma (msg, typeof (&foo));
R r;
void main(){
    auto foo_ptr = &foo;
    lyr(foo_ptr, r);
}
```

No, the type should be the same. I want to register lyr!(&foo) 
like this:

```
   fn [string] reg = [
      "foo": &foo,
      "lfoo": &lyr!(&foo)
   ];
```
