Issue #2784 has been updated by Yui NARUSE. Is this really a bug? There is no documentation and doesn't work; it is considered that there was no such function. So my understanding is, this should be feature request. Yeah, such function seems useful, but I don't have how it should works. ---------------------------------------- http://redmine.ruby-lang.org/issues/show/2784 ---------------------------------------- http://redmine.ruby-lang.org
