The biggest problem with "class << self" syntax is that it is hard to read in classes that have more than a handful or so lines. At quick glance you might not be able to tell if "def xxx" is a class method or instance method. However, with "def self.xxx" it is more easily recognizable.

Btw, I think its a small nitpick. Plenty of great code bases use "class << self".

Totally agree, that's why I said 'if all methods are class methods...', in which case class<<self should go at the top of the class body. If there are instance methods I prefer def self.bar.
