Changing namespace to outside of module

ruby-talk
1

Hello
I want to make my changes inside a module (all "required" files are inside that module XY)
because these changes should only work if the module is included.
Is there a way to change the Namespace to a specific path (like Root::ModuleA::ClassB, or UP::... relative like in dirs)?

module A
   class Array
     def myjoin
         ...
     end
   end

   [1,2,3].myjoin # not found
end

# Outside the module:
[1,2,3].myjoin # not found

Whats the namespace for core?
## like Main::Array

thanks

::Array

However, it's probably not a good idea to monkey-patch
the Array class globally.
I would strongly recommend you look up Ruby's refinements.

Thank you!
But: (how?) is it done (on class Array), so that only code that includes A (or inside the module definition) is affected? - Outside the module it should only work using [1,2].A::myjoin (the syntax is very wrong?)

What is the class for print, puts, etc ?
module X
   def self.p_NL(v)
   ::stuck_out_tongue: v,"\n"
   end
end

X::p_NL(1)

How can I see from which class is a specific method?
   def show_class_of_method(:meth)
      ???
   end
