It is useful to have Array return a repeated permutation. Rather than add another method, we could overload Array#at to take multiple indexes.

a = [ "a", "b", "c", "d", "e" ]
a.at(0)     #=> "a"
a.at(-1)    #=> "e"
#New stuff
a.at(0,1) #=> ["a", "b"]
a.at(0,0) #=> ["a", "a")
a.at([2,3]) #=> ["c", "d"]
a.at([-1,1]) #=> ["e", "b"]

Array#values_at already exists for this purpose:

a.values_at(0,1) #=> ["a", "b"]
a.values_at(0,0) #=> ["a", "a")
a.values_at(*[2,3]) #=> ["c", "d"]
a.values_at(*[-1,1]) #=> ["e", "b"]

Well, I am an idiot. Read through the array spec twice and missed it both times. Please close.
