Subject: Re: Array#first is not Array#[0]

Maybe is better using instance_methods instead

class MyArray < Array
   Array.instance_methods.each do |m|
    define_method(m) do
      "Here you go: #{super}"
    end
  end
end

irb(main):033:0> g=MyArray.new [1,2,3]
=> Here you go: [1, 2, 3]
irb(main):034:0> g.first
=> "Here you go: 1"
irb(main):035:0>
