%w can be nicely used here:

Ruby version 1.9.1
irb(main):001:0> %w{foo force spells}.each do |s|
irb(main):002:1* printf "Testing %p\n", s
irb(main):003:1> puts 'blah1' unless %w{force spells}.include? s
irb(main):004:1> puts 'blah2' unless s == "force" || s == "spells"
irb(main):005:1> puts 'blah3' unless /\A(?:force|spells)\z/ =~ s
irb(main):006:1> end
Testing "foo"
blah1
blah2
blah3
Testing "force"
Testing "spells"
=> ["foo", "force", "spells"]
irb(main):007:0>

Kind regards

robert
