I like the idea of not separating the two ways of logging, syslogging
and devlogging should be "the same" from the POV of a developer and then
should be able to be redirected differently.

See for idea: http://logging.apache.org/log4j/1.2/

In my code I'd like to write code such as

Logger.log('whatever', TYPE::DEBUG);
Logger.log('whatever', TYPE::INFO);
Logger.log('whatever', TYPE::WARNING);

and then (by default) throw = not log all TYPE::DEBUG messages and be
able to configure debug messages to go to another table/file/... if
needed, most probably together with other levels as well:

	- (Default to be defined): everything except DEBUG into syslog
	- if debug activate: everything including DEBUG wherever we want (in
addition to standard syslog)

My idea to go one step further but perhaps is not absolutely needed,
would be this (advanced) use case:

- configure a logger for method/controller of extension X as DEBUG
- whatever happens until the end of the end of the method call (not
possible without AOP) or until the end of the request (easy), in
whichever part of the code including Core, should be logged.

Cheers
