Yeah, point well taken.
Sooo, right now I'm wembleying towards having
scm_is_true --- return 0 for #f, 1 for everything else
scm_is_false --- return 1 for #f, 0 for everything else
scm_is_bool --- return 1 for #t and #f, 0 for everything else
scm_to_bool --- return 0 for #f, 1 for everything else
scm_from_bool --- return #f for 0, #t for everything else
Is there an advantage of having instead
scm_to_bool --- return 0 for #f, 1 for #t, else signal error
What about
scm_from_bool --- return #f for 0, #t for 1, else signal error
