...which I was careful to keep in mind while designing the interface. 
But for the implementation, I kept it as simple as possible for now.

Not sure whether we really need more levels.  (I note that all the 
elaborate logging facilities do have lots of levels, but that somehow 
leaves me unconvinced.)  Lets see.

which a *library* like sal cannot do

Honestly, I am not worried about the performance of the current 
implementation at all.  If it should ever become a bottleneck (esp. if 
we ever decide to enable logs in production builds), we could rather 
easily improve it (though by adding complexity), without (that's my hope 
having designed it that way) having to modify the interface.
