Same thing regarding export from index. And let's delay further changes to these classes. Whereas I agree that a class with only static members is simply an object, there are some minor differences that we need to consider (for example, docs are suddenly different).

Funny enough, ArrayTools isn't exported. This means it doesn't even appear in docs.

Sounds good, we can talk about this more on the forums.

If it is internal there is no need to export it, and there is no need to create an object for it. Can simply be converted to functions

Got it, I removed the ArrayTools object since it isn't exported and has no more internal references.
