macro difficulties

[Stefan Israelsson Tampe]

Hi,

I have some problem with syntax-parameters the use case is that I
would like to use both the old binding and the new binding at the same
time e.g.

(define-syntax-parameter a ...)

(...
  (let-syntax ((save (get-transformer a)))
     (syntax-parameterize
         ((a (syntax-rules ()
                ((_ x y) (save x y))
                ((_ x) ...)
                ...)))
        ... )))

I would believe that this is possible in master but how do I get this
semantic to work in guile 2.0?
