Ah! That's different!

The specification is simple: given a list of numbers, return the two which are nearest to one-another

I didn't parse the "one-" part (in my lame defense, my current window width wrapped the line right after the "-") so I was thinking you wanted the two numbers from a list closest to some other number not on the list.

So just ignore me. (:
