Or it could be about disambiguating local variable versus method call.
Hard to tell without more context.

Hi ,

Self.methods is static methods using the class name itself you can call
the
methods and is not available to the instance of the class.

There is no such thing as static methods in Ruby. self.method_name
(or sometimes self.class.method_name) are instance methods on the
singleton instance of the object (in 1.9 you can access the singleton
via singleton_class too). Since everything is an object in Ruby
(literally) you have multiple types of instances, in his case he is
accessing instance methods on the singleton (or anonymous class or
eigen, however you want to label it) vs instance methods on /an/
instance of that object.

class A
def self.b
print “this is static methods”
end
end

You can only be able to call the method “b” by using : A.b

that wat I am trying to say.
