Hello, I continue my work with Typed/Racket and Racket, and I now have another problem, with the same error.
I try to use in untyped racket a typed async-channel of type Any, and I'm not able to use the higher-order value from this channel. Here is an example code that show this problem : ``` #lang racket ; A higher-order value (define add (lambda (x) (+ x 1))) (add 1) ; Untyped is working well (require racket/async-channel) (define untype-p (make-async-channel 10)) (async-channel-put untype-p add) (define new-add (async-channel-get untype-p)) (display "untype world : ") (displayln (new-add 2)) ; Untype <-> type world doesn't work (module port typed/racket (provide build-port (struct-out port)) (require typed/racket/async-channel) (struct port ([channel : (Async-Channelof Any)])) (: build-port (-> port)) (define (build-port) (port (make-async-channel 10)))) (require 'port) (define p (build-port)) (async-channel-put (port-channel p) add) (define n-add (async-channel-get (port-channel p))) ; Fail : Attempted to use a higher-order value passed as `Any` in untyped code: #<procedure:add> (n-add 3) ``` Do you have an idea how I can use my procedure? I don't know if it's possible, or if it is a limitation of the untyped <-> typed boundary?
