Re: Question about typeof(this)

I'm reading http://www.digitalmars.com/d/2.0/declaration.html#Typeof 
where it says:

"typeof(this) will generate the type of what this  would be in a 
non-static member function, even if not in a member function. "

 From that I got the impression that the code below would print the same 
result, but it doesn't. It prints:

main.Bar
main.Foo

instead of:

main.Foo
main.Foo

Is this a bug or have I misunderstood the docs?

typeof(this) gives the *compile-time* type of this. Inside Bar, it has 
to return 'Bar'.
typeid(this) gives the *runtime* type of this. So it can work that it's 
Bar is actually a Foo.




module main;

import std.stdio;

class Bar
{
    void method ()
    {
        writeln(typeid(typeof(this)));
        writeln(typeid(this));
    }
}

class Foo : Bar {}

void main ()
{
    auto foo = new Foo;
    foo.method;
}
