You might use this code (I use it in gimp-mode):
(defmacro gimp-hash-to-list (hash-table)
(let ((nl (gensym)))
`(let (,nl)
(maphash (lambda (k v)
(push (list k v) ,nl)) ,hash-table)
,nl)))
(defmacro gimp-list-to-hash (list)
(let ((ht (gensym)))
`(let ((,ht (make-hash-table)))
(mapc (lambda (item)
(puthash (car item) (cadr item) ,ht)) ,list)
,ht)))
