From ab26623182bb94e1b29668d86b5ee387991926fe Mon Sep 17 00:00:00 2001 From: Robert Griesemer Date: Tue, 25 Feb 2014 09:13:37 -0800 Subject: [PATCH] spec: clarify default "true" condition/tag in for/switch statements An absent condition/tag in for and switch statements is equivalent to the predeclared constant true; not simply the expression true (which might lead to a locally defined true). Not a language change. Fixes #7404.
