Hi!

Adding new instance variable is done by calling a become: like
oldclassWithoutTheNewIV become: newclassWithTheNewIV

Therefore this operation requires some primitive in the VM. Is it necessary? If this mechanism is not implemented in Java is it only because the VM does not have a become: ?

Cheers,
Alexandre
