OK, we are in agreement about removing the $caller then.
I propose that we work on parameterised logging for 2.2 and consider
markers for the next release to achieve a smaller release cycle.
The logging methods will be rewritten to support:
Logger::debug($message); // standard
Logger::debug($m
The main logging methods (Logger::trace(), Logger::debug(), etc.) currently
take two parameters: $message and $caller.
I traced the path by which the $caller parameter is passed on and it goes
like this:
1. The main logging methods pass it to Logger::log()
2. Logger::log() passes it to Logger::f
