This is pretty much my thinking too. A programmer's choice to use [ ]
instead of {} the destructuring pattern means something. By choosing to use [ ]
as the pattern they are expressing the intent to view someValue using "array
element" access semantics. If they don't care about such things, they can use
the { } pattern.
