Yes, you are. :-) According to both the current C++ Standard and the
latest Working Draft. The Draft
www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2691.pdf says at
17.4.3.1.1, Namespace std [namespace.std]:
"The behavior of a C++ program is undefined if it adds declarations or
definitions to namespace std or to a namespace within namespace std
unless otherwise specified. A program may add a template specialization
for any standard library template to namespace std only if the
declaration depends on a user-defined type of external linkage and the
specialization meets the standard library requirements for the original
template."
Kind regards, Niels
