Ups, I am surprised that wrapped still has access
to func I thought that this would only work
with Python's lambda. My fault.
The pre/post calls are only executed once
when the file is loaded so this should be
handled with care...
However I do not need to pass pre/post as
parameters, so it does not matter very much.

The only drawback is that the code needs
to be separated into a fuction unless the
generator "hack" is used. So wrapfunc seems
to be the optimum so far.
