From 9c292fef316739f43730f11b9a2b6d3e4b725b54 Mon Sep 17 00:00:00 2001 From: Tom Sepez Date: Thu, 21 Jun 2018 15:02:24 +0000 Subject: Avoid const-refs to implicitly constructed strings. Because the invisible temporary goes out of scope at the next semicolon. Also avoid returning const string references since the cost is low to properly keep the string alive.
