Anyway, there are many different cell "behaviors" that I have to simulate, and cells can potentially gain and lose these "behaviors" over the course of the simulation. It would be too much to put every behavior function in the cell class, so I'm writing each behavior as a mixin and mixing it in (and initializing it) when necessary or when biological function is gained by the cells.
Perhaps you could keep the behaviors in a dictionary? You could
override __getattr__() in the cell class to look up attributes whose
names start with 'behavior' in the dict.
