Subject: Conflicting method names with modules

Hi,

I'm working my way through the Pickaxe book and am on Chapter 9 Modules.

I am a little confused as to how methods work if you mixin several modules 
containing identical method names. If you see the code below: how can I 
specify which method (testmethod) should be being called in the ScaleDemo 
initialize method? It appears that it takes the last module included as the 
method, but is there a way I can qualify it to take the other one?

Thanks,
Jon

PS Loving the language so far. :)

module MajorScales
        attr :numNotes
        def majorNum
                @numNotes = 7 if @numNotes.nil?
                @numNotes # Return 7
        end
        def testmethod
                puts "MajorScales test method"
        end
end

module PentatonicScales
        attr :numNotes
        def pentaNum
                @numNotes = 5 if @numNotes.nil?
                @numNotes # Return 5?
        end
        def testmethod
                puts "Pent test method"
        end
end

class ScaleDemo
        include MajorScales
        include PentatonicScales

        def initialize
                puts majorNum # Should be 7
                puts pentaNum # Should be 5

                testmethod
        end
end
