def method_missing(name, *args)
  # -- original perl comment --

  # There are two types of set methods: set_property() and

  # set_property_color(). When a method is AUTOLOADED we store a new anonymous

  # sub in the appropriate slot in the symbol table. The speeds up subsequent

  # calls to the same method.


  method = "#{name}"

  # Check for a valid method names, i.e. "set_xxx_yyy".

  method =~ /set_(\w+)/ or raise "Unknown method: #{method}\n"

  # Match the attribute, i.e. "@xxx_yyy".

  attribute = "@#{$1}"

  # Check that the attribute exists

  # ........

  if method =~ /set\w+color$/    # for "set_property_color" methods

    value = get_color(args[0])
  else                            # for "set_xxx" methods

    value = args[0].nil? ? 1 : args[0]
