Subject: Re: Please tell me what this means? self.<method> in a class


Additional remarks:

 - Preferably use "self" instead of the class name in order to minimize
the number of places in the code you have to touch if the class name
changes.

 - You can as well use the class << notation either way

class Test
  class <<self
    def foo() "foo" end
  end

  class <<Test
    def bar() "bar" end
  end
end

>> Test.foo
=> "foo"
>> Test.bar
=> "bar"

Of course you can define multiple methods with this in one
class<<self...end like for "normal" classes.

Kind regards
