I'd like to use something like

Pretty sure that's done for performance, so that if the thing being logged is a complex expression, but yet could be trivially filtered, it is not evaluated.
Oh, you mean if I use some #define MINIMUM_LOG_LEVEL 3 then some of these lines are not evaluated? If the respective parts were header only, I wonder if the same could not be done without the MACROS (but with compiler optimization). Regards, Roland
