The example in the guide works fine:
#lang racket
(provide main)
(define (any-double? l)
(for/or ([i (in-list l)])
(for/or ([i2 (in-list l)])
(= i2 (* 2 i)))))
(define (main)
(define p
(place ch
(define l (place-channel-get ch))
(define l-double? (any-double? l))
(place-channel-put ch l-double?)))
(place-channel-put p (list 1 2 4 8))
(begin0
(place-channel-get p))
(place-wait p))... which is strange, because 'p' is not a place-channel, and yet the call to (place-channel-put p (list 1 2 4 8)) succeeds. I'm guessing that calling place-channel-put with a descriptor pulls out the associated channel... should the docs indicate this? Also, my tiny experiments suggest that place-channel-put is blocking, is that right? John
