The definition of SCM_NEWSMOB is correct; its prototype is
SCM SCM_NEWSMOB (scm_t_bits tag, scm_t_bits data);
However, if you want to use a SCM value as the data of a smob, you
need to use SCM_UNPACK to convert that SCM into a scm_t_bits:
SCM_RETURN_NEWSMOB (scm_tc16_memoized, SCM_UNPACK (scm_cons (exp, env)));
