Deeply interacting with the compiler, how? Not through the public interface
of GC? Do you mean it is not used in a clean way?

Yes, I've seen it but it's a work in progress, and it's being rewritten from
scratch.

What exactly is the GC being used there? Is it a custom algorithm or a known
one? Could we plug our own algorithm to the oc4mc if it has already provided
the basic changes to substitute the GC?
