I agree. Ravioli code is particularly nasty because it fulfills "DRY" in the small but hurts the ability to make further changes. In both the spaghetti and ravioli situations a cyclical attack of "factor/inline/factor/inline" flushes away the worst stuff and reveals opportunities for more substantial changes, but it's easier to start from the case where there's too much inline code than to fumble through a deep callstack. That said, if your functions are pure functions, they won't contribute much to overall complexity. It's a much different situation from having a do_the_thing() method that does some mutability magic.
