From: "duerst (Martin Dürst)" Date: 2013-07-23T13:55:36+09:00 Subject: [ruby-core:56119] [ruby-trunk - Feature #8663] Officialy alias ArgumentError to ArgError Issue #8663 has been updated by duerst (Martin D��rst). This just saves 5 characters, but creates confusion because now many people will start to wonder what the difference is between ArgumentError and ArgError, if any. ---------------------------------------- Feature #8663: Officialy alias ArgumentError to ArgError https://bugs.ruby-lang.org/issues/8663#change-40619 Author: boris_stitnicky (Boris Stitnicky) Status: Open Priority: Normal Assignee: Category: Target version: When not using custom made exceptions, I find myself using TypeError, NameError and ArgumentError the most. ArgumentError is the longest and I would like to suggest to alias it officially as ArgError. -- http://bugs.ruby-lang.org/
