It would be interesting if there was a programming language that would make log messages and comments interchangable at runtime.
Many times you can follow code because of the comments, but often the log messages also provide a major clue into what is happening. But, you have to choose one or the other. Being able to choose both, where you're effectively setting logging level via syntax, might encourage more readable code.
