Regarding generate(): allWords should never be changed (generate is called in a loop with the same allWords every time) -- so should it be `in WordSet allWords`?
For parameters that shouldn't be changed, use const. So it should be `const WordSet allWords`.
Regarding update(): ladder and words are both modified in update -- so should they be `ref WordList ladder` and `ref WordSet words`? And if so, do I need to change the update() call in the generate() function?
Yes, they should be `ref`. No, you do not have to change the update() call.
compatibles is (will be) modified in generate() but not in update(), so should it be `in WordSet compatibles`?
It should be `const WordSet compatibles`.
