Sorry to reply to my own mail, but...

One thing to realise is that your object is still being extended by the
module.  If someone extends the module, your object will also be extended.

The idea I had doesn't have this problem.  (It does have the slightly larger
problem of being currently impossible in Ruby, though.  :)
