This is really nice in combination with defines and > macros that use ( ) around its content. >>From http://en.cppreference.com/w/cpp/language/decltype : Note that if the name of an object is parenthesised, it becomes an lvalue expression, thus decltype(arg) and decltype((arg)) are often different types. Now I don't know the exact rules for lvalue expression so I don't know if it is working the correct way or not.
