I don't think the distinction you mention exists. If self is SomeClass then def self.foo is the same as def SomeClass.foo, just more convenient.

If you really want to dig into it, I'd highly recommend The Well-Grounded Rubyist. Chapter 5 in particular.
No affiliation other than I was lucky enough to review it. Good stuff.
