I'll be sure to try it out in the next few days. Passing messages to a
separate logging thread seems like it might be a overkill, but it could
work. I do like that you can get the file and line included with messages.
One thing I'll miss from Log4J and its siblings is that typing
log.info("message")
is a lot more intuitive than log(LogLevel.info, "message"). I don't think
that's a major gripe though.
