Logger as an anonymous function. I think literally every logger let's you log at a certain point as a single line that does not cover the context of the log. logger.info('Doing this and that', function () { do_this() if(maybe) do_that() }) This way you know how much the log comment is supposed to cover as well as take a benchmark on the said context. I can never think to just add a single line logger anymore. This is much better than inserting comments in a code as comments can have no context except the line below. You can add a function like, logger.comment and don't let it log anything to be comment syntax replacement.
