 **Experimental Namespacing Lands in Ruby Master**
 
 - A new **experimental namespacing** feature [has been introduced in Ruby master](https://bugs.ruby-lang.org/issues/21311), allowing the creation of **virtual top-level namespaces**.
 - This enables applications to `require` or `load` libraries in isolation from the global namespace—including `.rb` files and native extensions. Dependencies loaded within a namespace remain confined to it.
 - Namespacing helps avoid **name conflicts** between libraries that define the same modules or classes, and prevents **unintended sharing of global objects**.
 - The feature opens the door for safer, more modular Ruby applications.
