Michael, I'm not sure to follow all the philosophical details of the issue. To
be sure:
1- __is_pod implements, to date, the correct C++0x semantics, modulo ISO DRs
(probably forthcoming, but a resolution seems quite far)
2- Thus, by definition, __is_pod is the right way to implement std::is_pod.
3- About tr1::is_pod, the issue is a little more muddled, but given my Comment
#7, we cannot really do wrong as regards TR1 is concerned (and, frankly I don't
care much about TR1). Note that the semantics of tr1::is_pod already changed
once, when __is_pod started to be used as an implementation detail.
All in all, if you ask me, until the ISO DR issue is resolved I don't think we
should do anything here.
