> Will refactoring take 50% less time because you won't need to properly
understand what goes on before you do it, or because you dislike
sequences of variables needing to be renumbered?

because I can now move and swap function calls without constantly
checking and amending the signatures all over the place - which for me
is a massive overhead.
