Hi @xFAR! Thanks for the contribution.

I'd like to accept this pull request, but I've got a couple minor issues:

• Our coding convention requires four spaces be used per indentation level than one tab
• We have a macro (admittedly difficult to discover!) called NS_COLLECTION_THROW_IF_NULL_REASON; you can place it at the top of this function and keep the rest of the code the same.

NS_COLLECTION_THROW_IF_NULL_REASON(indexes, @"indexes must not be nil");

Would you mind writing tests (in NSArrayTests.mm) for this method (with a nil index set) as well? You can use the other tests as a template.

Dustin, My responses inline.

I will update the style. I use tabs equal to four spaces so I did not notice.

Ok.

Would you mind writing tests (in NSArrayTests.mm) for this behaviour as well? You can use the other tests as a template.

Hopefully, I can get to this later in the week.
