Issue #2829 has been updated by Marc-Andre Lafortune. Hi Yusuke. Thanks for these comments. I've updated the wiki accordingly. I've also added examples to most exception classes. Unless there is objection, I plan on changing the following error messages: [1, 2].fetch(-3) From: index -1 out of array To: index -3 outside of array bounds: -2...2 {}.fetch("foo") From: key not found To: key not found: "foo" I will also commit the changes documentation unless there are further comments. -- Marc-André ---------------------------------------- http://redmine.ruby-lang.org/issues/show/2829 ---------------------------------------- http://redmine.ruby-lang.org
