Subject: Re: Defining a method with an argument with a default value

[Warning: Anal retentive refactoring ahead]

define_method(:initialize) do |*values|
  case values.size
  when 0..1
    @value = values.first
  else
    raise ArgumentError, "wrong number of arguments (#{values.size} for
0)"
  end
end

or perhaps

define_method(:initialize) do |*values|
  @value = values.shift
  unless @value.length == 0
    raise ArgumentError, "wrong number of arguments (#{values.size} for
0)"
  end
end

Too... many... options... ahh!
