From: "robertgleeson (Robert Gleeson)" Date: 2012-11-21T03:17:27+09:00 Subject: [ruby-core:49773] [ruby-trunk - Feature #7414] Now that const_get supports "Foo::Bar" syntax, so should const_defined?. Issue #7414 has been updated by robertgleeson (Robert Gleeson). I realise defined? with a constant works just as well but this is about API constancy. I'd expect const_get & const_defined? to support the same query language ("Object::Foo"). ---------------------------------------- Feature #7414: Now that const_get supports "Foo::Bar" syntax, so should const_defined?. https://bugs.ruby-lang.org/issues/7414#change-33356 Author: robertgleeson (Robert Gleeson) Status: Open Priority: Normal Assignee: Category: Target version: 2.0.0 class Foo end Object.const_get "Object::Foo" => Foo Object.const_defined?
