Going that route, there will always be one more function that someone
wants to be converted. Third-party libraries also often won't be able
to handle generated lists without modification. OTOH, by modifying
SCM_CAR/SCM_CDR, everything that handles lists automatically becomes
able to handle generated lists, and the cost for normal lists is only
the same cost as when compiling with -DSCM_DEBUG_PAIR_ACCESSES=1.
