Subject: invoking class method within class definition

Hi,
    consider following code:

#!/usr/bin/env ruby
class Foo
	def self.bar
		puts "class method called"
	end

	def some_method
		Foo.bar              # -----> self.bar will not work here
	end
end

foo = Foo.new
foo.some_method

although I can define the class method using "self", I have to use
class name to invoke the class method within the class. it would be
nice if I can invoke class method without explicitly using it's name,
so when I change my class name, I only need to change it in one place.
any way to do this?

Thanks!
