Not when you're teaching the language to undergraduates: I haven't
actually done the study yet (though I may this summer), but I'm willing to
bet that allowing "math" notation for sets will more than double their
use.  (Imagine having to write "list(1, 2, 3, 4, 5)"...)

"...however, the issue could be revisited for Python 3000 (see PEP 3000)."
So I'm only 1994 years early ;-)
