Yes. The external representation is effectively an int. Btw any closure can
be passed <-> the external world under the type representation scmobj which
is effectively an int also, look it up in the manual.
I'm not clear right now if scmobj:s are persistent to GC iterations though,
if you/anyone knows please let the ml know.
