[Python-ideas] Logging Levels

[Mike Miller]

Hi, IMHO the prior decision(s) are too conservative.  Reading the bugs, we can 
see lots of folks reinventing the wheel with common use cases for no good 
reason.  I also gave examples in the log4j, docs, and web apps world that these 
levels are recognized needs.

An addition would represent a very tiny fractional increase in the complexity of 
the logging module, from ~6 to ~8 in one small corner.  It's not like we're 
adding human expressions to cats and piles of poo here are we?  ;-)

The builtin java logging suffers from backwards compatibility with an awkward 
initial design.  log4j doesn't (nor we) have that problem, but it includes some 
cases suggested.

In short, have been using note and fatal for years productively.  Not a strong 
proponent of trace and have survived without it so far, but if it were there I'd 
have used it a few times over the years.
