Heterogeneous lists

[Gordon Airporte]

This is one of those nice, permissive Python features but I was 
wondering how often people actually use lists holding several different 
types of objects.
It looks like whenever I need to group different objects I create a 
class, if only so I can use more meaningful names than '[2]' for the items.
How often do these show up in your code?
Is this simply the upshot of the underlying arrays holding only object 
references of some sort?
