That looks like I'm buoying my idea.  I think any single one of these
methods will work just fine.  I'm somewhat leaning towards [1..-1]
because it's very clear what's happening.

I'll stick with my #shift for now because it makes logical sense to
me.  I'm not overly concerned in my work with speed or memory use.
James knows what he's talking about so really listen to him.
