This is way more friendly to both users and implementors.
Iterableis an absolute PITA to work with, both for users, when a method returnsIterable, and for implementors, when a method accepts it. And there are no interesting types which implementIterablebut notCollection.Now, I considered making the substitution
Iterable->Collection, but really all that allows isSets. And here, in lifecycle methods,Setactually has the wrong semantics, because the returned values are correlated with input values by their order.So
Listis really the right thing to use here!
