I'm afraid I don't know how to do this, but data conversion is
definitely in the set of C API operations that I think should be
documented.

Absolutely, but this is possible and much easier to do from Scheme,
isn't it?

But it isn't pedagogy just for the sake of it.  I anticipate big
benefits in documentation and elsewhere, e.g. in the management of
updates between releases.

Yes, exactly, except that in practice the last of these may never
happen - and that isn't actually so bad, because for core hacking you
will probably need to read the code anyway.  In fact, the best
documentation for core hacking is probably extensive commenting in
difficult areas of the source.

Thank you!
