Yes, this should work. Record accessors expand into simple
component access ("return(abc->xyz);" / "abc->xyz=VAL;").

That way you have full control of allocation and make the result
GC-able. You probably want to use `foreign-primitive' for that.
It's a perfectly viable alternative.
Another approach might be SWIG (www.swig.org). The current
cvs version has even better Chicken support, thanks to John Lenz.
