Oh, let me say something explicitly: You guys are Ruby committers, you are the ones that have the vision for what makes sense in the language. I am raising a flag because this does not square to me, and makes me feel it is introducing a leaking abstraction not backed by the language model. It is an abstraction you could tolerate in Active Support with documented caveats, but not one that I personally see in Ruby itself. However, if once the feedback has been listened to you believe this API squares with your vision of Ruby, by all means go ahead :). ---------------------------------------- Feature #17753: Add Module#namespace https://bugs.ruby-lang.org/issues/17753#change-91511 * 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/
