It should return

~~~ruby
::Baz::Bar.namespace
# => [Foo::Bar, Foo]
~~~

I haven't read through the issue, but what is the issue here?

Feature #12317: Name space of a module

----------------------------------------
I want a method to return the  name space of a module, something like:

~~~ruby
class A; module B; module C end end end

A::B::C.namespace => [A, A::B, A::B::C]
~~~

There is `nesting` method that is similar, but that only returns the lexical nesting information.

There are also some known hacks for this, converting the module to the string representation using `to_s` or `name`, and then splitting it by `::`. But that easily breaks if the module is anonymous, or is a singleton module. I would like a more robust, core method.
