The example looks great, exactly what I'd hope for in the way of a 
logging library. A few questions:

  * How do you disable logging at compile time? (and is it zero overhead?)
  * How do you define your own logging backend?
  * Is it possible to change logging options after initialisation?

There are a couple of features missing, but you seem to have mentioned 
planning to implement these elsewhere in the thread. Once they're in 
place I'd be happy to vote yes to its inclusion into phobos.
