Implementation wildcard operator for pattern-matching-like case statements in RUBY

Ruby pattern matching wild cards

#Here is a quick implementation of pattern matching for cases in ruby
module WildcardFunctionality
  class Wildcard
    def ==(other)
      true
    end
  end

  def _
    Wildcard.new
  end
end
                
class Object
    include WildcardFunctionality
end


#class MyClass
#  def test_a_case_statement
#    digital_data = [1,1,1]
#
#    case digital_data
#    when [0,1,1] then puts "match"
#    when [_,1,1] then puts "match 2"
#    else puts "couldn't find match"
#    end
#  end
#  def test_another_case_statement
#    first_name = "Andrew"
#    last_name = "Huxley"
#
#    case [first_name,last_name]
#    when _ then puts "found the name"
#    else puts "didn't find the name"
#    end
#  end
#end
#
#my_class = MyClass.new
#my_class.test_a_case_statement
#my_class.test_another_case_statement
