Yeah -- Peter Otten explained in more detail, but summing up: what you
need is a Factory Design Pattern -- a function that takes the encoded
data, decodes it, instantiates the appropriate class (probably based on
a dict to map code->class) with the appropriate parameters.  No reason
whatsoever to have an instance mutate its own class in this case.
