Get the modules included into a class object

Ruby
1

If I say:

module Foo
def zim; end
end
class Bar
class << self
include Foo
end
end

Bar.zim is now available

How can I find out which modules are included into Bar at class-level.

Some attempts:

Bar.included_modules
Bar.class.included_modules
Bar.class.new.included_modules
Bar.ancestors
Bar.class.ancestors
Bar.class.new.ancestors

None of them return anything with Foo in it.

Query the class into which you included the module:

class << Bar
ancestors
end
