Hi All,
I was wondering whether it's at all possible to change the class of an already existing object. This is purely theoretical, so forgive me if this is against all the best practices.
As a hint, what I have in mind is something along the lines of Perl's (yes, indeed...) bless() function.
Thanks,
-Max

No, an object retains its "birth class" forever. I think there might
be some 3vi1 libraries out there that manage to bring this about 
But the basic design is that the class doesn't change. (Of course you
can change literally everything about the object's actual behavior,
what methods it has, etc.).
