I don't think so. initialize it's just an instance method, just like
any other, with the same lookup path:

irb(main):001:0> module M
irb(main):002:1> def test; puts "test from M"; end
irb(main):003:1> end
=> nil
irb(main):015:0> class A
irb(main):016:1> include M
irb(main):017:1> def test; puts "test from A"; super; end
irb(main):018:1> end
=> nil
irb(main):019:0> A.new.test
test from A
test from M

Jesus.
