Martin mentioned in a review of your code that he remmbers it not being
safe on at least one compiler. I have not encountered such a compiler,
and I know that I'm doing it with non-type template parameters in the
traits code.
The last time I checked HP aCC 3 didn't support unnamed template
parameters. There should be a record of the bug in our Bugzilla.
aCC 3.63 does appear to support them but due to a bug I uncovered
while checking I wouldn't say it's safe to get into the practice
of relying on it just yet:
$ cat t.cpp && aCC -V -c t.cpp
template <class, int> struct S { };
S<int, 0> s;
aCC: HP ANSI C++ B3910B A.03.73
aCC: Not enough memory is available to finish the compilation.

Or is this safe practice?
