First time I heard the term &quot;most vexing parse&quot;. However, I know what it is and created a patch in g++ to provide a warning for it, back in 2008:<p><a href="https:&#x2F;&#x2F;gcc.gnu.org&#x2F;bugzilla&#x2F;show_bug.cgi?id=36587" rel="nofollow">https:&#x2F;&#x2F;gcc.gnu.org&#x2F;bugzilla&#x2F;show_bug.cgi?id=36587</a><p>(Apparently they ignored it because evidently &quot;enhancement&quot; items in the gcc Bugzilla are not how you submit patches).
