Issue #21316 has been updated by tagomoris (Satoshi Tagomori). Status changed from Open to Closed Now the name of classes defined in a box is just its name. ``` ./exe/ruby: warning: Ruby::Box is experimental, and the behavior may change in the future! See doc/language/box.md for known issues, etc. {name: "C", eq: true} MBA:build s-tagomori$ RUBY_BOX=1 ./exe/ruby -v ruby 4.0.0dev (2025-12-09T12:29:36Z box-news-documents.. c998717de8) +PRISM [arm64-darwin24] MBA:build s-tagomori$ ``` ---------------------------------------- Bug #21316: Namespaces leak with permanent names https://bugs.ruby-lang.org/issues/21316#change-115541 * Author: fxn (Xavier Noria) * Status: Closed * Assignee: tagomoris (Satoshi Tagomori) * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN ---------------------------------------- Namespaces are not transparent for this program ```ruby C = Class.new C.name == 'C' ``` because under a non-main user namespace, the name of `C` has the namespace as a prefix. -- https://bugs.ruby-lang.org/
