What are we going to do about code like this:
(define foo (make-parameter 0)) (define bar (delay (foo))) (parameterize ((foo 1)) (force bar))Does this return 0, 1, or either? All the Schemes in my test suite that support SRFI 39 return 1, so the question is whether we standardize this or permit implementations to return 0. This would be plausible if the delayed expression were executed on a separate thread starting at delay time, in the manner of futures.
