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

# include the same text in all my array elements. I just want to have
# some fixed text attached to ANY operations I do with array elements.

there are other better ways, but i just extended your initial thought/code,

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

g=MyArray.new [1,2,3]
#=> Here you go: [1, 2, 3]
g[1]
#=> "Here you go: 2"
g[0]
#=> "Here you go: 1"
g.first
#=> 1
g.last
#=> 3
g[-1]
#=> "Here you go: 3"
