By haf:

I suggest making it possible to pass a delegate from `Unit -> String`, something like [this](https://github.com/jkowalski/NLog/blob/master/src/NLog/LogMessageGenerator.cs) because it'll make deferred logging much smoother and avoid spending CPU cycles computing the ToString of the objects going into the log.
