Do you mean the following situation?

# file mystring.rb

  module MyMod

   class String
    
   ...

   end
  
  end

In this case, you're right. This piece of (pseudo) code creates the class 
MyMod::String, which is a completely different thing from the String class. 
If you want to extend String, you simply have to move the class 
String;...;end part outside the definition of module MyMod:

# file mystring.rb

  class String
    
  ...

  end

  module MyMod
  ...
  end
 
I hope this help
