Pretty direct, I'd say. I wouldn't even have introducing *methods* as
an initial goal. My experience is that trying to re-engineer while you
translate is a dangerous rathole - you can easily end up at a place
where you've lost track of the semantic mapping between the original
code and the translation, and are just wandering around thrashing.
