How to add module namespace to a ruby class/module?

I want to add a namespace to a class/module I'm defining, but I don't want to type in the long format

class A::B::C::D::<ClassName>

OR

module A
  module B
    module C
      module D
        class ClassName
        end
      end
    end
  end
end

In other words, I just want to define the class class ClassName and then need a way to send this class to live under the namespace A::B::C::D

So that I can write a bunch of code like so:

# File Name: a/b/c/d/some_class.rb
class SomeClass
  include SomeModule
  # class content
end

# File Name: a/b/c/d/some_module.rb
module SomeModule
  # module content
end

Because there are too many modules in my codebase, I don't want to type in the prefixing namespace everytime. But I want to say something like this at the end:

SomeClass.add_to_namespace(A::B::C::D)
SomeModule.add_to_namespace(A::B::C::D)

Important: This should also affect class namespace lookup so that Ruby/Rails doesn't complain like:

expected a/b/c/d/some_class.rb to define SomeClass

Question: Will include-ing my class in the namespace have the same effect?

module A::B::C::D
  include ClassName
end

It seems like what you're asking is kinda multi-faceted, but if you just want to use the class in another file without having to type out the namespace each time then a simple solution would just be to redefine it in the file you want to use it in

ClassName = A::B::C::D::ClassName

Then you can just do ClassName.method just fine
