> What happens on reblessing?
An excellent question, and one that has been exercising my mind for
some time now.
I have come to the conclusion that a reblessing must either:
* invoke the old class's DESTROY(s) and then invoke the
new class's SETUP(s), or
* invoke some other hierarchy of automagic methods
(REFIT? RESHAPE? MORPH? TRANSMOGRIFY?), or
* do nothing.
The first behaviour is by far the safest, but would seem to defeat the entire
purpose of reblessing.
The last behaviour is the most flexible but forfeits guaranteed clean-up.
The middle option is annoying because it adds yet another magic method.
But suspect it is the correct response.
