Title: Updated methods.include? with :each (from "each")

Just a small update changing line 6 in about_iteration.rb from:

assert_equal __, [].methods.include?("each")

to:

assert_equal __, [].methods.include?(:each)

All of my books have it this way (and "each" did not work on my install (Ruby 1.9.2)).
