The only thing I see in the manual is `scm_assert_foreign_object_type`.
For something equivalent in scheme, I guess you could do something like:
----------------------------------------------------------------------
(define (foreign? obj)
(not (or (number? obj)
(string? obj)
(null? obj)
;; and so on..
)))
----------------------------------------------------------------------
I agree that such predicate should be part of the buitlin API.
