No matter what, you'll somehow need to do something like:
// equivalent of: BOOST_LOG (some_log) << the << things << to << output;
if ( is_enabled(some_log)) some_log << the << things << to << output;
Which to me seems tedious and you can easily forget to write that.
Yes, something like that is necessary. I also agree that it is tedious and easily forgotten. The question is whether there is a way to capture that idea in such a way that it cannot be forgotten without adding additional overhead or tedium.
I'm certainly open to suggestions ;) I've thought about it for quite a while, and couldn't come up with a solution. If any of you has any idea about improving this, please speak up...
