I agree, defaulting to LogLevel.all was a bad choice. I also 
think that std.experimental.logger shouldn't setup a logger by 
default. It's very easy for a user to opt in using `sharedLog = 
new MyLogger();` I'm happy for phobos to include a Logger 
implementation but the default behaviour should be to not output 
anything unless a Logger has been explicitly assigned to 
sharedLog.
