Removing items from a list about blessed HOT 2 CLOSED

Since there is no removeItems method, I've been looping over the items array and removing each one with removeItem, for some reason, looping forward removes only every second item! but, looping in reverse from the last one works fine, for instance...

Because every time you remove and item by index, it gets spliced out, so the items.length changes. If you want to remove all items, you could do list.setItems([]).

I'm okay with a removeItems method. That sounds like a decent idea.

Ah, I didn't think it was a real array (since there was no removeItems
mothod I assumed removeItem was abstracted to prevent the exact problem I
described). Anyway, setItems([]) would kill everything which only addresses
that use case.
