But now I'm prepared to flip-flop again because I just discovered that
JPython (which is what I use most of the time) doesn't support the "new"
module -- so the "create a subclass on the fly and change the __class__
attribute of the instance" approach just became a lot more appealing to me.
:-)

In the absence of the "new" module it seems like its either 1) use the
approach above or 2) use the earlier suggestion of "add a method to the
class, retrieve a bound method using the 'dot' syntax, assign that to the
instance, then delete the method from the class".
