Raymond, I think you're overestimating how often the repr() of a set
actually gets eval()'ed. I expect this happens approximately never. I
certainly haven't used it myself, and most certainly not in a
performance-critical context.
The reason that repr() returns an eval()'able expression isn't that
the expression is likely to be eval()'ed -- it is that the programmer
is already familiar with the notation and can thus immediately
understand what it means.

because the list is just a distraction.
