Maybe the patch be better with:

 def dump(self,init_state=None, ids=True, mems=True)
    ...
    if init_state is None:
        init_state ={}
    ...
    for variable, value in self.modified(init_state, ids, mems):
        ....

Is it ok for you ?

Hmmm just note that modified doesnt take in a state instance as the name implies but a base dictionary as its commented in the source code (so a dict(state) )
@init_state: a base dictionary linking variables to their initial values

So I guess passing dict() of a StateEngine or correcting the modified func as well.

Well, as the state is a kind of dictionary, I may keep the dictionary as argument if you are ok with this (the .symbols return a dictionary as well)
