hard to say. so many options!

1. use the lower number as start and the higher number as stop. it would "work" more often but might produce unexpected behavior
1. return an empty array, in which case at least any future operations won't throw 'nil has no method'
1. raise an exception

I think [avdi's talk, slides 31-36](http://avdi.org/talks/confident-code-railsconf-2011/) advocate option 3
