Thanks for all the help.

So, on learning that I could subclass the number types, I didn't even  
consider the fact that they're immutable. I feel slightly foolish.  
And I'll look at gmpy straight away, it looks like it contains  
functionality I'll find useful.

I not sure that would be suitable in this case. I'm using genetic  
algorithm code containing some methods that assume 'individuals' are  
represented as bitstrings, and some that assume individuals are  
represented as lists of integers. Ideally, I could have created a  
class for the bitstring individuals that also supported list based  
bit assignment (without too much overhead).
