meta classes

[Carlo v. Dango]

hello there

I'd like to take control over the method dispatching of every subclass of a 
given python class. Currently I've redefined __getattribute__() so i can 
find the right instance/method to dispatch to. This works fine, albeit it 
may seem a bit hackish. Further I want to control the actual dispatching, 
so that I can execute methods before, after or instead of the actual 
method. I would prefer to do this with the least modification of the source 
due to debug'ing issues. My best idea so far is to rename every method who 
subclass the magic class X and then create new methods in place of the 
renamed ones, which looks up in a list to execute "before-methods", then 
execute the renamed method etc..

Only I don't know how to do this. I've found some MOP code which was 
designed for python old-style objects... but this is not what I want. Can 
anyone kindly give me some pointers for help or some actual code?

many thanks in advance..
