It would have been even nicer if I only needed to specify it once per class, but, well, in my case this hardly matters. The code below works as intended. One problem (not specific to the code): the decorator destroys the signature: it always becomes "*args, **kwargs"). This is annoying with help(), but what worries me most is that my Sphinx documentation is also affected. The information about the defaults gets lost (the parameters are decribed in the docstring, but not the defaults). That kind of sucks. Is there a builtin way around this (in other words: I am aware of this package: https://pypi.python.org/pypi/decorator). I am hoping to get the code working on Python 2.7 and 3.3 and up.

Thank you! Luckily, decorator.py is just one file, so I could easily include it. Version 3.4 is needed, because of a bug in an older version. Now I still need to find out how to create a git submodule to a hg repo, where the decorator package is. :-)
