But i don't understand. For what i've read inject combines all element of an array by applying a method or block on each How come inject uses the Numeric#+ instead of my Item#+ since all elements are items??????? That puzzled me Does someone understands that? It don't make sens to me -- Posted via http://www.ruby-forum.com/.
