robert,

Quite right, I'm not sure Ruby is particularly suited for role
swapping. (Prototype-based OOP handles it gracefully) And I don't know
how inefficent #become would be. It would be nice to think its just a
matter of changing one pointer, but I know that's not the case.

Your role delegator is nice. At the very least it's much easier to be
more than one thing at a time. (There's no problem with roles
interfereing with each at the method name level is there?) Unfortuately
I suspect that it may be nearly as inefficient as repeated using
#become (but that's just a guess).

Thanks for the illustration, I think I'll store this for potential
future use/exploration.

BTW, does #unrole actually work?
