I only know of GOOPS and Theme-D -- Guix also has a
‘define-gexp-compiler’ but it's very ad-hoc.
It allows defining something like
(define (lower stuff system target)
(cond ((derivation? stuff) stuff) ; done
((foo? stuff) (lower (lower-foo stuff system target)))
((bar? stuff) (lower (lower-bar stuff system target)))
[...]))
(where 'lower-stuff' converts 'stuff' into something 'lowerable'),
but in an extensible way.

Maxime.
