import std.stdio;

class Foo
{
    this() { o = new Object(); }
    Object o;
    alias o this;

    override string toString()
    {
        return "Foo";
    }
}

void foo(Object o)
{
    writeln(o);
}

void main()
{
    foo(new Foo());
}


The code compiles, and prints "Foo". After discussing with Andrei, I believe this code is an error.

Yah, it's a simple case of unreachable code - the alias this would never ever get a chance. This needs to be rejected.
