After rereading this whole thread, I am still unclear: what is a proper way to implement there stateless keywords?
look at boost/parameter/keyword.hpp
Will do.
Also I believe in many other places I am using type& within unnamed namespace. This seems to be valid usage, right?
You've left out too much detail for me to make a determination.
This is essentially boost/test/trivial_singleton.hpp:
#define BOOST_TEST_SINGLETON_INST( inst ) \ namespace { BOOST_JOIN( inst, _t)& inst = BOOST_JOIN( inst, _t)::instance(); }
Here inst ## _t is type of singleton and inst is a reference to the instance
If your question is whether you are allowed to use references inside unnamed namespaces, the answer is yes. I note that you are still using dynamic initialization above. Using brace-initialization is important to avoid order-of-initialization problems. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com The Astoria Seminar ==> http://www.astoriaseminar.com
