Expanding macros

[Panicz Maciej Godek]

Hey,
is there any legitimate way to expand the scheme macros
to the scheme code in guile 2.0?
The macroexpand procedure seems only to compile the code
to the tree-il language (no matter whether 'e, 'c or any other
symbol is passed as a second argument):

(macroexpand '(define (f a b) (list a b)) 'e)
; ===> #<tree-il (define f (lambda ((name . f)) (lambda-case (((a b)
#f #f #f () (a-4236 b-4237)) (apply (toplevel list) (lexical a a-4236)
(lexical b b-4237))))))

thanks
