Class should be a Class.class, a Class.class.class.class and so on.

[c910335]

Though I have mentioned this on Gitter, I think this issue should be submitted.

code

pp Class.class
pp Class.class.class
pp Class.is_a?(Class)
pp Class.is_a?(Class.class)
pp Class.is_a?(Class.class.class)
pp Class.is_a?(Class.class.class.class)
pp Class.is_a?(Class.class.class.class.class)
pp Class.is_a?(Class.class.class.class.class.class)
pp Class.class.is_a?(Class)
pp Class.class.is_a?(Class.class)

result

Class.class # => Class
Class.class.class # => Class
Class.is_a?(Class) # => true
Class.is_a?(Class.class) # => false
Class.is_a?(Class.class.class) # => true
Class.is_a?(Class.class.class.class) # => false
Class.is_a?(Class.class.class.class.class) # => true
Class.is_a?(Class.class.class.class.class.class) # => false
Class.class.is_a?(Class) # => true
Class.class.is_a?(Class.class) # => false
