Some restrictions on this are necessary -- it obviously
wouldn't be safe to allow replacing the class of an
object with one having an incompatible C layout, and
most built-in types have their own unique layout.

I think it's easier in Ruby, because all objects in
Ruby look pretty much the same at the C level. Not
sure of the details, though.
