Thanks for your post -- sorry it took so long to respond. Couple of point=
s:

* Seems like parts of what your implementation provides are already=20
available in Log::Log4perl, namely the "stealth loggers" feature. I'm=20
almost sure you've read these two docs, just in case:

http://log4perl.sourceforge.net/releases/Log-Log4perl/docs/html/Log/Log4p=
erl/FAQ.html#what's_the_easiest_way_to_use_log4perl
http://log4perl.sourceforge.net/releases/Log-Log4perl/docs/html/Log/Log4p=
erl.html#stealth_loggers

It autocategorizes all loggers based on the class a particular logger is=20
in, but at compile time and not at runtime.

* What your implementation provides on top of that, is the=20
categorization based on function names and line numbers.  I think the=20
first one is a useful feature. The 2nd one I find somewhat doubtful,=20
because line numbers change quickly as a program evolves and it's=20
probably better to control messages with "message filters" if you need=20
to be able to intervene at such a low level.

* I also find the "coverage" feature very useful, we should probably=20
have that in Log::Log4perl.

Not sure what you're referring to here. The stealth logger docs mention=20
ways to simplify the init (like easy_init({file =3D> ..}). Let me know=20
what you mean exactly if I missed anything.

All in all, in looks interesting and I'd certainly be interested in a=20
complete distro to install and play with -- are you planning on=20
providing that?
