Yes, it would work ... but Brent already landed a workaround for
MSVC - http://trac.webkit.org/changeset/156516/trunk/Source/WTF/wtf/StdLibExtras.h

It would be great to have a general fix. I'll upload what I meant in a minute.

Argh, it was already fixed in http://trac.webkit.org/changeset/156529

Sure, I cancel r? and cq? for this one and wait for your fix.

Thanks!
