[racket-dev] set operations

[David Van Horn]

The set library is missing a convenient way of selecting an element from 
a set, making it hard to write recursive functions matching the 
inductive structure of a set.

Could you add this function, or something like it?
(define (set-choose s)
  (let ((x (for/first ([x (in-set s)])
             x)))
    (values x (set-remove s x))))
