Pimp my Log()
summary
Macro-plus-template logging that packs streamed arguments into nested pairs so the compiler sees a single call and can optimize away intermediate operator<< calls. Uses expression templates and a log_data chaining operator to build packaged argument pairs at compile time, yields about 73% fewer instructions in the tight loop benchmark, and trades runtime call overhead for more instantiations and larger binary text. No compile-time penalty numbers are given.
