I do not follow.

1. Tango passes a const(char)[] around [1]. What is the 
difference?
2. Have you looked at the doc and the impl. of FileLogger? They 
both show an easy how to implement a Logger without the GC. With 
that it is also trivial to make a MultiLogger that does not 
allocate. BTW, the default implementation is a direct result of 
the "by default multi-threading safe" requirement brought up 
multiple times during reviews.
