BTW, I should also point out that when compiling on MSVC 6.0 only "Integral
_T" (pbv) is available since it is required for explicit casts which are
temporary non-l-values.  That means MSVC 6.0 clients are forced to use the
pbv form with the potential for unnecessary tempories but I think the
compiler is pretty good about eliminating them, though alas no l-values on
6.0.
