Will this module be published for others to use? If so, can I suggest a
feature?
One thing that's really important with logging, but rarely available, is
not levels, but code areas. I believe python, for example, allows you to
name log sections:
logger("mainsection.subsection.subsubsection1", "message1")
logger("mainsection.subsection.subsubsection2", "message2")
and then you can enable, say, everything related to "subsection", but
then filter out everything in "subsubsection2".
That's really important, when debugging/auditing complex apps, without
actually wanting to modify the code just to find out what's going on.
Especially since modifying the code can CHANGE what's going on.
