Subject: Calling super with no arguments

Hi all,

Does anyone know how to invoke super so that it passes no arguments to
the superclass' method?

For example:

class A
  def initialize
    puts "making an A"
  end
end

class B < A
  def initialize var
    puts "making a #{var} b"
    super
  end
end

B.new "great"

results in:
making a great b
/tmp/super.rb:10:in `initialize': wrong number of arguments (1 for 0)
(ArgumentError)
        from /tmp/super.rb:10:in `initialize'
        from /tmp/super.rb:14:in `new'
        from /tmp/super.rb:14

Because calling super with no arguments causes the method's arguments
to be repeated.  How do I stop this?  Temporarily, I stuck a *args on
class A's initialize method but that is not pretty!
