in thread (Golf) Nearest Neighbors

Any solution which returns a pair of numbers that are in the list and represent a minimal distance from each other with respect to all other possible pairings is correct. We are comparing the distance between all possible number pairings, and returning a minimal one. So the following are all correct: 
nn(1,5,9,15) returns (1,5)
# or
nn(1,5,9,15) returns (5,9)
# or
nn(1,5,9,15) returns (9,5)

I don't really understand the beginning of your question though.

    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. (:
