Subject: Re: Using any trick to omit () in constant lookup?

or an idea, forgot your Button class, and override const_missing

def Object.const_missing(name)
  if name == :Button
    if $use_gtk
      return Gtk::Button
    else # else use something else.
    end
  else
    super
  end
end


so:

p Button #=> Gtk::Button


but it think Gunther has the better idea
