Issue #18883 has been reported by qnighy (Masaki Hara). ---------------------------------------- Bug #18883: parse.y: trailing comma cannot coexist with star https://bugs.ruby-lang.org/issues/18883 * Author: qnighy (Masaki Hara) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-linux] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- The following code is a syntax error: ```ruby *x, y, = 1, 2 # syntax error, unexpected '=' ``` although the following: ```ruby x, y = 1, 2 # OK x, y, = 1, 2 # OK *x, y = 1, 2 # OK # *x, y, = 1, 2 ``` In my understanding, the trailing comma does nothing unless the lhs becomes otherwise a single assignment. Therefore it is natural to allow the trailing comma whether `*` exists or not. -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
