Here's a good function header given the following:
I wrote the below code

    conflict_list = []
    def add_conflict(fval1, fval2, path):
        conflict_list.append(path)
        return fval1
    unify(fstruct1, fstruct2, fail=add_conflict, trace=trace)
    return conflict_list

What's a good function header?
