The repr is the model for how we enter things by hand.
If the repr is set([1,2,3]), the that's how we will learn
to type them into our programs.  It's not the eval(repr(s))
round trip that's at issue, it is a question of the preferred
way to write code.

I'm at a loss for words to explain the reasons for my strong
aversion to the syntax.  All I can say is that I think it's a mistake
and hope you let me switch back to the Py2.6 way.
