Interesting: for the same purpose, I would define __repr__.

But I still define it only when I actually care about the details, since 
otherwise the default __repr__ is always there.  Spending time figuring 
out a potentially more useful __str__/__repr__ (how nice that we've 
confused the issue of which to use, again! ;-) ) is not my idea of a 
good use of time, what with YAGNI and all from XP...
