I would like to be able to do either of these two solutions:
<input type="checkbox" name="items[id]">
<input type="checkbox" name="items.id{{id}}">

Why?

So that I can refer to 1 variable in the scope and treat it as an array of checkbox values. You can have all the keys set to the value specified by the checkbox (or just 1 by default). This seems a lot more reasonable than having to deal with functions that manually handle the data when you check or uncheck.
