For instance, instead of

BOOST_LOG_SEV(slg, normal) << "A regular message";

I'd like to use something like

slg.log(normal) << "A regular message";

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.
