Bar.new.foo

That's called subclassing, deriving or inheritance.

Just do

class Bar < Foo
end

Bar.new.foo

Note that you can derive from one class only. All others have to be
(included) modules.

If we can define a class method called "source" that can get class's
source ,then
include_class method will be defined

class Foo
include Enumerable
def foo
end
end

Foo.source #=>
# include Enumerable
# def foo
# end
