No, but it doesn't really need it. Note that there are two different 
flavors of #become: in the Smalltalk world - the swapping version and 
the forwarding version (if that is the right term).

The equivalent of the non-swapping version can easily (but not 
efficiently) done as

     a _RemoveAllSlots.
     a _AddSlots: b.

The swapping version is just a little more complicated.
