From: Magnus Holm <redmine@...> Date: 2010-06-11T04:12:06+09:00 Subject: [ruby-core:30719] [Bug #3422] Object.const_get(:A, false) can access BasicObject::A Bug #3422: Object.const_get(:A, false) can access BasicObject::A http://redmine.ruby-lang.org/issues/show/3422 Author: Magnus Holm Status: Open, Priority: Low Category: core ruby -v: ruby 1.9.2dev (2010-05-31 revision 28117) [x86_64-darwin10.3.0] From the documentation of Module#const_get(sym, inherit=true): If the constant is not defined or is defined by the ancestors and inherit is false, NameError will be raised. Yet, this works fine: BasicObject::A = 1 Object.const_get(:A, false) # => 1 While I haven't tested it, I believe the attached patch should fix the issue. ---------------------------------------- http://redmine.ruby-lang.org
