class VirtualMethodCalledError < RuntimeError

  attr :name

  def initialize(name)

    super("Virtual function '#{name}' called")

    @name = name

  end

end



class Module

  def virtual(*methods)

    methods.each do |m|

      define_method(m) {

        raise VirtualMethodCalledError, m

      }

    end

  end

end





# The usage is beautifully simple:



class VirtualThingy

  virtual :doThingy

end



class ConcreteThingy < VirtualThingy

  def doThingy

    puts "Doin' my thing!"

  end

end



begin

  VirtualThingy.new.doThingy

rescue VirtualMethodCalledError => e

  raise unless e.name == :doThingy

end

ConcreteThingy.new.doThingy
