will be done, see the reply to Sönke's post.

I thought about that, but I'm not sure if that won't the logger to
complex.  IMO it is better to have some reasonable hard-coded default
than a log format parser. If the user needs something else, subclassing
a logger and changing the format is a 7 liner. And this is the design
Idea behind the logger.

logf("name %s, taskId %s", name, taskId); already works

Thanks, keep it coming
