Subject: Re: Generation of initialize

Hi again,

I'm trying to enhance the previous solution (shown again at the end).
I'd like to call the initialize method of the superclass from the
generated initialize. For the moment it's ok to call it without
parameters. Simply placing super inside the method definition doesn't
work. Can anyone explain me how to do it. Thanks in advance.

def initialize_with(*params)
  define_method(:initialize) do |*args|
    if args.size != params.size then
      raise ArgumentError.new("wrong number of arguments"\
        " (#{args.size} for #{params.size})")
    end
    params.zip(args) do |param, arg|
      instance_variable_set("@#{param}", arg)
    end
  end
  return params
end
