There's something called Object#become in Ruby 1.8 but I don't quite get
its purpose. I have not seen doc for that method yet, but it seemed to be
nearly an alias for #replace ??

Long ago I had written a quick hack implementing Smalltalk's #become in
Ruby. The patch as-is was simply rejected, for good reasons; but after
that, no-one was interested in improving it, making the necessary fixes to
it, etc.
