[plt-scheme] local syntax-case macro does not see earlier macro

Hi,

The following works fine:


==============
$ cat test.scm
(define-syntax foo (syntax-rules () ((_) "It works!")))

(define (f) (let-syntax ((bar (syntax-rules () ((_) (foo)) ) )) (bar) ) )

#;(define (f)
  (let-syntax ((bar (lambda (x) (syntax-case x () ((_) (foo)) ) ) )) (bar) ) )

(display (f)) (newline)
==============
$ mzscheme -e '(require scheme)' -f test.scm
It works!
==============


But if you choose to use instead the equivalent commented definition of f, you get:


==============
$ mzscheme -e '(require scheme)' -f test.scm
reference to undefined identifier: foo

 === context ===
test.scm:8:20
==============


Why is this so?

Marijn
