I'm certain that this was recently answered on this group, but I can't
seem to find it. For instance, if I am using #lang racket/base, how would I
figure out that I need "racket/contract"? (my current solution is "grep" or
Google ... but I was hoping for a more elegant solution).
#lang racket/base
; obviously, I would need: (require racket/contract)
(provide (contract-out
[great-stuff (string? . -> . string?)]))
(define (great-stuff s) "not implemented")
