Review comment:
       I was trying to get all this path without iterators which would be ideal, but `indexes.values()`
is a `Collection` which I can't access via `get()`. The previous streams would have the same
array conversion, which is suspicious as the immediate solution would be to use the `ArrayList`.
Being the hot path maybe we want to keep the 'pure' array index access even though `ArrayLists`'s
overhead might be minimal if anyting at all. Sounds good?
