Smart pointers are rarely used, most C++ stuff is done by value.Strings too?
Two string types are used.-std::string type: by value, has smaller buffer optimization, used at startup/logging, and for any dynamic strings with unbounded possible values
-immutable string handles: by value. When created it looks up into a hash to find or create that string. Two immutable strings with the same value, will always use the same pointer(like Lua). These are never destroyed, they are intended as handles.
