you get a nifty `KeyError` saying there is no `category` in the format
expansion dictionary. If you add `category='auth` to the
`app.logger.info()` calls and its cousins, its fine, because these methods
use the magic `\*\*kwarg` argument to swallow it. Everything goes well until

two things: `info()`, `error()`, and co. pass `*args` and `**kwargs` to

present in its definition to swallow it. A little doc reading later I found
that if I want to pass extra arguments for such a formatter, I should do it
via the `extra` keyword argument to `\_log()`. A call like
via the `extra` keyword argument to `_log()`. A call like
`app.logger.info('invalid password', extra={'category': 'auth'})` solved the
problem. Now *that* is tedious.

repeating code. I changed the specification a bit, so my calls would look
like `info('message', category='auth)` instead of the original plan of
`info('auth', 'message')`: as the logging methods pass all keyword arguments
to `\_log()`, I can handle it there. So at the end, my new logger class
only patches `\_log()`, by picking out `category` from the kwarg list, and
to `_log()`, I can handle it there. So at the end, my new logger class
only patches `_log()`, by picking out `category` from the kwarg list, and
inserting it to `extra` before calling `super`.
As you can see, this is a bit ugly solution. It requires me, the app
