Hello.

While trying to get some piece of parser code be covered by tests (I'm 
translating the DMD parser to Java) I found that this is possible:

---
alias class Foo {
}

typedef class Bar {
}
---

What those attributes in a class suppose to mean? Just curiosity.

The grammar for alias and typedef is
alias Declaration

I don't know what the above means, I think it's not legal D code, I 
think the compiler would complain about it, but, at the semantic pass. 
At least that's what I have assumed.

I don't know what this code is supposed to mean, but it seems to compile and
run:


import std.stdio : writefln;

alias class Foo {}

typedef class Bar {}

void main()
{
    Foo c = new Foo();

    writefln("Looks like nonsense to me, but the compiler doesn't mind.");
}
