Could you clarify what you mean by that? Are you concerned about
methods like #instance_variable_set and #class_variable_set? Or more
generally about the fact that code like:

class Foo
  @bar = 12
end

creates an instance variable on the fly at runtime, without requiring
some sort of
  instance @bar
line that 'declares' it before use?
