 OK, but I want to do the same with normal methods

G>   require 'example'      # Includes class A, which defines A#foo:pre,

                            # and define a private method a

     # I just want to define a method a


G>   class A
G>     def foo:pre(*args)
G>       puts "Calling A#foo(#{*args.join(',')})"
G>     end

        def a
           puts "a"
        end

G>   end

 You have the same problem actually with methods, perhaps you just don't
 see it
