I guess that's the most common operation on regular event, we just want a sub-array from the beginning. We may update this later if needed.

We may document the behavior though, to ensure the user can understand the clause. I'll add an issue on the dojo-book to ensure that we describe better what's available and how. :)

Thanks for the work done here mate!
