Which works but neither dmd nor gdc were able to optimize the
additional function call away.
pragma(inline, true)
auto funcptr (alias method) ()
Thanks. Just found that
```
template funcptr (alias method) {
enum funcptr = &method;
}
```
works on both dmd and gdc. This gives rise to questions:
Is this code expected to compile and pass its unittest?
```
struct S {
void bar () { }
}
enum ei = &S.bar;
immutable i = &S.bar; // line 6
const c = &S.bar; // line 7
unittest {
import std.stdio;
writeln (ei);
writeln (i);
writeln (c);
}
```
gdc passes while dmd says:
```
$ dmd -unittest -main -run ini
ini.d(6): Error: non-constant expression `& bar`
ini.d(7): Error: non-constant expression `& bar`
```
Is this consistent?
