Self

README.txt

Regarding the self convention, within both a class method, and the class itself, 'self' refers to the given class, however when called 
within an instance method, self refers to a specific instance of that class.

class Person 
	def self.example_class_method
		puts "We're calling an example class method"
		puts "'self' is always defined. What is 'self' here? Let's see"
		p self #Person
		puts "That was self!"
	end

	def example_instance_method
		puts "We're calling an example *instance* method"
		puts "'self' is defined here, too, but it means something different"
		p self #Person Object/instance of the class (#<Person:0x007fa3e30fa990>)
		puts "That was self, again, but see how it's an instance of the class"
	end 

	puts "You'll see this as the class is being defined"
	puts "in this context self is:"
	p self 
	puts "See? self is the Person class"
end
