Which is why I am so elated by the Traits work... <:)

Also, I agree 100%, in smalltalk, what matters is that two objects speak 
the same protocol, not that they somehow inherit in an appropiate 
fashion on the tree... ( The horrors of the JAVA collection classes ).

I think Traits in a way may be a combination of several ideas used in 
Smallscript. It seems they're like mixins/interfaces/etc depending on 
how much is implemented inside them...

That said, Traits should make implementing PIE easy...
