It seems to me that, when doing a high-level language binding for a
library, it makes sense to take advantage of features of that language.

For example, when I did my Python binding for Cairo, I took advantage
of Python’s data-manipulation facilities to offer high-level operations
on geometrical objects.

What is Prolog good for? The resolution convention.

So how can you use resolution in a Cairo binding? Perhaps combine a
getter and setter into a single predicate, that can resolve either way?

But that means implementing some kind of functional interpretation of
Cairo objects.

Now there’s a rabbit hole...
