type-stubs

This extension provides a module which exports stubs for Chicken's type syntax when used with Chicken versions below 4.7.5 which is the version this syntax was introduced with. With Chicken versions >= 4.7.5 it doesn't export anything. This allows code to be type annotated and still be excuted and compiled with older Chicken versions.

Example

(module my-typed-module

(doubled-number->string)

(import chicken scheme)
(use type-stubs)

(: doubled-number->string (number -> string))
(define (doubled-number->string n)
  (number->string (* n n)))

)
