module Virtual
  # our machine is made up of objects, some of which are code, some data
  #
  # during compilation objects are module Virtual objects, but during execution they are not scoped
  # 
  # So compiling/linking/assembly turns ::virtual objects into binary that represents ruby objects at runtime
  # The equivalence is listed below (i'll try and work on clearer correspondence later)
  #  ::Virtual            Runtime / parfait
  #   Object                  Object
  #   BootClass               Class
  #   MetaClass               self/Object
  #   BootSpace               ObjectSpace
  #   CompiledMethod          Function
  #   (ruby)Array             Array
  #         String            String
