Hi All,
The program below gives this error:
.... collects/racket/stxparam-exptime.rkt:11:4:
syntax-parameter-value: contract violation
expected: syntax-parameter?
given: #f
Why?
/Jens Axel
#lang racket
(require racket/stxparam
racket/splicing)
(define-syntax-parameter *types* 'foo)
(define-syntax (display-types stx)
(displayln (syntax-parameter-value #'*types))
#'(void))
(splicing-syntax-parameterize
([*types* 'baz])
(let ()
(display-types)
(splicing-syntax-parameterize
([*types* 'bar])
(display-types))
(display-types)))
