+ added full support for member operator + added full support for std::iostream operator + implemented perfect forwarding for actor + adapted some test cases for "best-practice" + implemented variadic arguments for all actors based on phoenix/core/limits.h + added proper boost build handling + arity calculation tweak from Eric [SVN r63027]
