Could somebody explain why this http://dpaste.dzfl.pl/248262b9 return this:
Foo:

7FBFD59A80
Bar:
7FBFD59A58

Why this value in ctor is different from this value out of ctor if ctor
gets an argument?
Because in D Classes are reference types. That means the code you wrote
is equivalent to the following C++ source:
class Foo
{
public:
Foo(Object* o)
{
printf("%x\n", &this); // print a Foo**
}
}
class Bar
{
public:
Bar()
{
printf("%x\n", &this); // print a Bar**
}
}
void main()
{
Object* o = new Object;
Foo* foo = new Foo(o);
printf("%x\n", &foo); // print a Foo**
Bar* bar = new Bar();
printf("%x\n", &bar); // print a Bar**
}
My best guess would be that you wanted to pass "this" instead of "&this"
to writeln as weel as "bar" instead of "&bar" etc.
