ISTM that the stdlib is a special case here. If you're writing an application then the "No handlers could be found" message is actually useful because there's hardly any reason no to include one. If you're writing a library, well, that depends. Part of libraries might want to have their specific default handlers, part of them might want to leave that to the library user (e.g. "No handlers can be found" by default) and part of them might want to silence logs by default. One way or the other, we should really default to the convenience of application developers. This is currently the case. -- Best regards, Łukasz Langa tel. +48 791 080 144 WWW http://lukasz.langa.pl/
