Is it possible for an object to change at runtime what it appears to
be, to the rest of the program? For instance, if I have two types of
object, say WTFoo and WTBar, can I make another one under some name
(WTMorphy, for example) which can pretend to be WTFoo & WTBar, as it
likes? i.e. I get an instance of WTMorphy, tell it to be a WTFoo, then
at some later point it changes itself to a WTBar?
I know this sounds strange, and I'm not pretending it's necessarily a
good idea to ever actually do, but I'm curious if it's possible. I can
think of a couple of instances where it might be worth testing this,
depending on how well it can be done.
