This is what I was going to bring up. I'd also like to add that it was
a wonderful decision on Norbert Crombach's part to name the method
Array#rand rather than Array#random so that confusion and/or annoyance
would set in were one to attempt to add another method to Array that
attempts to use random numbers. Oh, also the Rails core team in
general for not bringing this up and accepting the patch without a
comment.
