Yes. ‘scm_from_pointer’ is pre-2.0.0.

Yes, but it’s consistent with the other scm_{to,from} functions.

I’m happy with this change. Mark?
(Back then, I was skeptical about the usefulness of the C pointer API.
I have since used ‘SCM_POINTER_VALUE’ and ‘scm_from_pointer’ in
Guile-GCC, which uses a mixed dynamic/static FFI, and for good reasons.)
Thanks,
