this yields only a modest speed up and only when iterating
over long sequences, e.g. like in this program:
#lang racket/base
(require racket/sequence racket/contract/base)
(define s (make-string 10000 #\a))
(define str (contract (any/c . -> . (sequence/c char?))
(λ (x) (in-string s))
'pos 'neg))
(time
(for ([x (in-range 100)])
(for ([x (str 0)])
(void))))
