Sorry, I missed the "not IMO a valid a generalization about OOT".  Still
it seems to me that most everyone uses frameworks nowadays - their own, or
pre-made.  I agree with you that given the mechanics and language
differences it's almost impossible to reuse a class/object from one
environment in another.  But that doesn't make the goal for reuse within
the same environment any less important.
