   I would still feel more comfortable calling str(), even if it passes 
straight through to a __repr__ -- as with a lot of cases in Python.

   I'd be interested to know what the general Python approach to Unicode is. I 
guess it'd be nice to just seamlessly move from python 1.5 & Qt 1.x to python 
1.6 & Qt 2.x with no buggering around with repr() ;)

   I've just had a poke around, but couldn't find any concrete information on 
how Unicode in Python is going...
