With the proviso that "Traits is a dead end" is a completely separate
discussion (and one that I seriously disagree with - take a look at
all the languages that have picked up traits and run with them), I'm
specifically referring to the duplication. Actually, I'd rather rip
#rename: out of Class and drive it where it belongs, in Environment.
But that's something that needs more discussion.

But in particular, traits don't fit well into the system because
_noone did the work_. Pharo still has this problem, because _noone's
done the work_.
