But to initialize non-null fields, I suspect we would need to be able to

class Bar

Foo foo = new Foo();

}
Which would be lowered by the compiler into this:
class Bar
{
// Assume we've already checked for bogus assignments.
// It is now safe to make this nullable.
Nullable!(Foo) foo;
this()
{
// Member initialization is done first.
foo = new Foo();
// Then programmer-supplied ctor code runs after.
foo.dummy = 5;
}
}
I remember C# being able to do this. I never understood why D doesn't
allow this. Without it, I have to repeat myself a lot, and that is just
wrong ;).]
It is not sufficient.
class Bar{
Foo foo = new Foo(this);
void method(){...}
}
class Foo{
this(Bar bar){bar.foo.method();}
}
