Another weirdness between Ruby 1.8 and Ruby 1.9
stuff = (1..10).to_a
# => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
stuff = stuff.detect { |stuff| stuff.even? } ? stuff : 'none found'
#### Ruby 1.8 #######
# => 2
# So, #detect first runs, finds 2 and the result is reassigned into "stuff"
# the ternary operation follows, with "stuff" set to 2

end
