Code that already uses `struct-type-info' would break. And that code
(and yours) would break every time we want to add something new. For
that reason, I think it makes more sense to add functions.

As far as I can tell, it ignores inspectors.

You can certainly get around inspectors (or any other language-enforced
invariant) with the FFI.
