Subject: Psyco compatibility

Hi!

First of all thank you for continuing the Psyco project and for your  
engagement in PyPy.

Next, I would like to ask a stupid question regarding the  
compatibility with peak.rules:
The web site of peak.rules clearly states, that psyco shouldn't be  
used to optimize generic functions:
---
It generates custom bytecode for each generic function, to minimize  
calling and interpreter overhead, and to potentially allow  
compatibility with Psyco and PyPy in the future. (Currently, neither  
Psyco nor PyPy support the "computed jump" trick used in the generated  
code, so don't try to Psyco-optimize any generic functions yet - it'll  
probably core dump!)

Okay, I still have many other functionality, which I would like to be  
optimized, e.g. genshi, sqlalchemy:
So my plan was to bind these manually:

But it turned out, that it wasn't even possible to import psyco and  
peak.rules at the same time:

python
Python 2.6 (r26:66714, Nov 30 2008, 13:50:14)
[GCC 4.0.1 (Apple Inc. build 5490)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import psyco
>>> import peak.rules
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/michael/programming/owpdb4env/lib/python2.6/site- 
packages/PEAK_Rules-0.5a1.dev_r2600-py2.6.egg/peak/rules/__init__.py",

line 207, in <module>
    "when", "Extend a generic function with a new action"
TypeError: unbound method make_decorator() must be called with Method  
instance as first argument (got str instance instead)
>>>

By the way, this does *not* occur, if I type the import commands in  
ipython.

The used PEAK_RULES version is
PEAK_Rules-0.5a1.dev_r2600-py2.6.egg


freshly installed from PyPI.
Psyco 2.0 is affected as well as 1.6.

So, here is the actual question: Is there something special happening,  
when importing psyco?
