even more weird:
---

import std.conv;
interface Meh{
final string typeName()
{return to!string(this);}
}
class Parent : Meh {}
class Child : Parent {}
void main() {
auto p = new Parent;
auto c = new Child;
assert(p.typeName == __MODULE__ ~ .Parent);
This is almost the same code as written initially,
let somone explain why the hell this is working:
---
module test;
import std.conv;
class Parent {
@property final string typeName() {
return to!string(this);
}
}
class Child : Parent {
}
void main() {
auto p = new Parent;
auto c

doesn't work. And similarly to the the orginal post:
I suggest to read some D documentation first, and program later.

I think it's a bug that you can use a template this parameter
(this T) on a static member function without a direct compilation
error.
