I'm trying to expand a task manager to optionally use places and I'm
having some trouble understanding the issue.
; test.rkt
#lang racket
(provide start)
(define (start thnk)
(sync (place ch (place-channel-put ch (thnk)))))
; x.rkt
#lang racket
(require "test.rkt")
(start (thunk 'ok))
Result: ; identifier used out of context: #<[...]/test.rkt:5:19 thnk>
I know that the place is creating a submodule which closes over the
place id ('ch') and the top level declarations, meaning only 'start'.
The argument to start is not at top level so it's invisible in the
submodule, meaning that the place code can't use it.
I feel like parallelizing a function at runtime should be a primary
use case for places but I'm not sure how to progress. Things I tried:
*) Passing the thunk in via place-channel-put, but functions are
place-message-allowed? #f.
*) Creating a top-level parameter into which I put the thnk at
runtime. Same problem.
Am I fundamentally misunderstanding something?
