Clang has warnings about using local regular expression objects and recommends creating them statically, but seemingly only when the pattern isn't QStringLiteral. Is it an oversight in clang's detection system or stringliteral'd regular expressions are so much cheaper that it doesn't deserve a warning?
I've delved into qt sources for a bit, but it doesn't seem like string literal dodges the necessity to compile a regex so I assume clang's detection is incomplete, right?
