Issue #17753 has been updated by shioyama (Chris Salzberg).
Regarding your proposal, in English would be `parent_module` right?
My interpretation here, but to me "parent module" would signify the "parent thing that is a module" of the current thing (whatever that thing may be), whereas "module parent" would signify the "module's parent", implying the _parent_ could be anything (but kind of implying it is also a module). English-wise as a method name either is possible, they just have slightly different emphasis. I suggested `module_parent` because it exists and is being used for the same thing, so there's a precedent, which might make it easier to agree on. ---------------------------------------- Feature #17753: Add Module#namespace https://bugs.ruby-lang.org/issues/17753#change-101757 * 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/
