There's a third way:
class B { ... } # introduce B as a class name without definition
class A { sub foo { B::bar } }
class B { sub bar { A::foo } }
The first line is a literal "..." in the body of the class -- it
indicates that we're only declaring the name as being a type,
and that something else will fill in the details later.
