Module Mixin & Class Variables

Ruby
1

Hey,

I would like to understand better what happens when one includes a
module with class variables inside a class.

===

module MyModule

@@test = “test”

def self.my_test
puts “From Module”
puts @@test.object_id
end
end

class B
include MyModule

def self.my_test
puts “From Class”
puts @@test.object_id
end
end

B.my_test
MyModule.my_test

From Class
-607833218
From Module
-607833218

===

Doing so, the output shows that in both cases the @@test object is the
same. Does someone have the big picture about class variables look up
while mixin a module inside a class?

Thanks,
