despite two (related?) flaws:

(1)
../Python/symtable.c: In function `symtable_visit_expr':
../Python/symtable.c:1209: warning: enumeration value
`Set_kind' not handled in switch

(2)
>>> {(x for x in range(10))}
KeyError: 'unknown symbol table entry'
>>> 

(Don't ask me why that was the third thing I tried with the
new syntax. :-)

Also, I'd love set comprehensions!
