Description

Consider the following code using class instance variables:

class Car
  def self.total_count=(n)
    @total_count = n
  end

  def initialize
    self.class.total_count = 0
  end
end

The compile requires "self.class.total_count" as the more readable "class.total_count" is mistaken by the parser as a faulty class definition.

How about adding a __class__ method to Object?

class Object
  def __class__
    self.class
  end
end

It would allow the use of "__class__" as a de facto prefix for class instance variables and would fit e.g. the id/__id__ and send/__send__ paradigm.

-1 because:

a) __class__ is more keystrokes (if you count the shift key)
b) self.class is clear (and exists currently)
c) I feel that __something__ should ideally be reserved for special cases; self.class isn't. I am aware that __FILE__ was used a lot before and there's talk about __dir__, but I think that require_relative is now a better solution for most of these cases.
