Another weirdness between Ruby 1.8 and Ruby 1.9

detect_and_ternary_op.rb

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

#### Ruby 1.9 #######
# => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
# So, the ternary operator is invoked before the result of #detect is reassigned into "stuff"
