The following patch makes post hook get the result of the hooked function. THis lets you do cool stuff like pre/post-conditions (like synchronization, they can be optional), but it is most likely rather slower than the current hook, which means synchronized classes will be slower. I have a working implementation of pre/post conditions based on this, if anyone's interested. *** hook.py Sun Nov 18 20:02:59 2001 --- hook.py-new Sun Nov 11 11:31:17 2001 *************** *** 48,55 **** --- 48,58 ---- none of the hooks raise an exception).
