Object Model

Methods

Block

  • Blocks are not objects -> Proc are
  • Block contain both the code and a set of binding.
  • When a block is defined. It grabs the bindings that exist at that moment(not in the method) and carries them.
Scope
  • The previous bindings will be replaced by a new set when enter a new scope
  • Whenever the program changes scope, binding set will be replaced except instance variables of a method which call another method on the same object
