Just releasing pre-expanded code might help:

  guile> (sc-expand '(define-syntax foo (syntax-rules () ((_ x) (+ x x)))))
  (void)
  guile> (sc-expand '(foo x))
  (+ x x)

One problem with the current syntax-case implementation is
that it loses original variable names and source properties.
This makes debugging a little bit hard.
