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 executed and compiled with older Chicken versions.

Constraints

In order to be fully compatible with older Chicken versions it is required to always provide an else branch in the compiler-typecase form. This is because pre-typed Chickens have to always use the else branch even when compiling code.

Example

(module my-typed-module

(doubled-number->string)

(import chicken scheme type-stubs)

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

)
