Issue #17753 has been updated by shioyama (Chris Salzberg).

When you assign an integer to a constant, it's just storage. If you assign a class or module object with a name, it's just storage. However, assigning an anonymous class or module object changes the state, it has a side-effect that is only programmed for these objects.

That's a very interesting way to put it, I hadn't thought of it that way. And indeed those side-effects scale with the number of other classes and modules rooted in the thing that was named. ---------------------------------------- Feature #17753: Add Module#namespace https://bugs.ruby-lang.org/issues/17753#change-101730 * Author: tenderlovemaking (Aaron Patterson) * Status: Open * Priority: Normal ---------------------------------------- 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.outer_scope`, or to `A` like `C.outer_scope.outer_scope`. I want to use this in cases where I don't know the outer scope, but I want to find constants that are "siblings" of a constant. For example, I can do `A::B::C.outer_scope.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.outer_scope.constants end ``` I've attached a patch that implements this feature, and there is a pull request on GitHub [here](https://github.com/ruby/ruby/pull/4326). ---Files-------------------------------- 0001-Add-Module-outer_scope.patch (5.93 KB) 0001-Add-Module-namespace.patch (5.89 KB) -- https://bugs.ruby-lang.org/
