I just could not resist, I am still amazed - after 20 years of Ruby
experience 8-], how easily things can be done, when did I say Ty the last
time Matz? Probably 20 years ago!!!

Ty Matz!!!

for those who like the notation,  very, very lazily tested, but amazingly
simple, probably rather slow etc....

module Enumerable
    class MapProxy
        def initialize obj
            @obj =3D obj
        end #def initialize obj
        def method_missing name, *args, &blk
            @obj.map do
                | ele |
                ele.send name, *args, &blk
            end
        end #def method_missing name, *args, &blk
    end #class MapProxy

    alias_method :aliased_map, :map
    def map *args, &blk
        return MapProxy.new( self ) if args.length.zero? && blk.nil?
        aliased_map *args, &blk
    end #def map *args, &blk
end #module Enumerable
