why doesn't this work:

####################################
class Test
     def foo_bar(x)
        puts x
     end
end

test = Test.new

puts 'guess the method:'
while gets
     if test.respond_to?($_)
         puts 'correct!'
         exit
     end
     puts 'incorrect guess, please try again:'
end
