That's what Meyer did, it's called Eiffel.  Really.  Ada83 was a big
influence.

Absent this, the problem here in 9x can be "solved" by a nearly transparent
change to the language:  say "cyclic dependencies in types, but not
initialization expressions, are now allowed."  like
it always should have been, in my opinion.

Now you can declare an X which has a component of type/package/class/whatever
Y, and have Y which has a component of class X.

It's not transparent to the compiler implementors, but no fix
here would be.
