That sounds about right to me.  Aren't there two separate issues here? 
'become', to me, means "become another **object**", not "change your
class".

I don't even know what

  x = X.new
  x.class = Y

is supposed to mean.  But I do understand the idea behind this:

  x = X.new
  y = Y.new
  x.become y

Are the two ideas really one and the same in this thread?
