PROBLEM with comments.py in current SVN

Good morning list and especially Ryan,

I recently took the plunge to update my little outdated installation  
to the current trunk version for testing.
I started by updating the plug-ins from the version in SVN. After  
upgrading comments.py my site stopped working (it hung during load).
No error messages, nothing. Since the old comments.py worked I had a  
look at what changed. Stepping through the changes I noticed the  
following.
Every occurence of "has_key" had been replaced by "in". This isn't a  
big deal. Well not for all the dicts in there BUT entry seems to give  
problems.

I am running on python 2.3 (version the host provides to me). Doing a

  if 'num_comments' in entry:

just hangs while

  if entry.has_key('num_comments')

works.
In and has_key are implemented differently. If there is no  
__contains__ in the class in iterates over every entry and I guess it  
gets stuck somewhere.
Just changing every occurence of "in" back to "has_key" for the entry  
case gives me a working system again, but I am wondering if this is a  
general problem or one with my setup.

Can someone cross-check this with his setup, before I commit the change?

Kind regards,
Michael
