Hmm, I should read code before posting. logf() etc. are using 
stdThreadLocalLog so this does what I want:

shared static this() {
  auto ml = new MultiLogger();
  ml.insertLogger("stdout", new FileLogger(std.stdio.stdout));
  ml.insertLogger("applog", new FileLogger("applog.txt"));
  stdThreadLocalLog = ml;
  logf("This is a test"); // works :)
}


Minor nitpick: This isn't clear in the docs of std.logger. 
Throughout sharedLog is referred to as the "default" logger, not 
stdThreadLocalLog.

Other than that I'm finding std.logger is really easy to use, 
nice work Phobosians!
