I created something to help address this... the "obvious" solution
of a decorator used for making decorators. It's example #6 in:
http://www.python.org/cgi-bin/moinmoin/PythonDecoratorLibrary
Currently it doesn't handle argspec, but I propose adding argspec
(it'll be slightly tricky, but shouldn't be impossible), then
including it in a "decorators" package. Until we have a decorators
package, I think it can live in the wiki and/or the cookbook.
If asked to do so, I'll see about updating this to fix the argspec.
If not asked to, I'll probably leave it alone, because as-is it is
simple enough to serve as a decent example as well as being useful
but with argspec handling it would be complex enough to be useful
but too complex to be a good example to learn from.
