If you are to dive into such low-level things, you could implement in Scheme type tag "deciphering". You'd use the `object-address' procedure, and then re-implement type tag encoding/decoding from "libguile/tags.h" at the Scheme level. That'd be an interesting exercise as the Scheme implementation would be readily understandable (compared to obscure C macros and informal comments). Otherwise, Andy's suggestion may be wiser. ;-) Thanks, Ludovic.
