Description

(reported by Imran Rafique)

The following fails:

 (module foo (bar baz)
 (import scheme chicken)
 
 (define (baz x)
   (print x))
 
 (define-syntax bar
   (syntax-rules ()
     ((_ x) (baz x))))
 
 )
 
 (import (prefix foo f:))
 (f:bar 1)

If the export list is replaced by `((bar baz))`, then it works. The reason is that the SE of `bar` in the former case does not contain `baz`.

Update: this example works if the module and the import are compiled, separately. So the cases where it fails are:

• module loaded and imported in the interpreter
• module compiled and imported in the same unit
