Given code like this:
```ruby
module A
module B
class C; end
class D; end
end
end
```
We can get from `C` to `B` like `C.namespace`, or to `A` like
`C.namespace.namespace`.
I want to use this in cases where I don't know the namespace, but I want
to find constants that are "siblings" of a constant. For example, I can
do `A::B::C.namespace.constants` to find the list of "sibling" constants
to `C`. I want to use this feature when walking objects and
introspecting. For example:
```ruby
ObjectSpace.each_object(Class) do |k|
p siblings: k.namespace.constants
end
```
