Yeah, this seems to be the best answer in this situation. :)

I would skip the cleverness of trying to subclass string. You can use

Well, here's what I am really doing:
class oneStim(str):
def __init__(self, time, mods=[], dur=None, format='%1.2f'):
self.time=time
self.mods=mods
self.dur=dur
self.format=format
def __cmp__(self,other):
return cmp(self.time,other.time)
def _
