I think what this means is that it's time for the Order object to become more full-fledged.

i.e. we should define the fields in the `__init__` method of the Order.

such as:
```
def __init__(self):
    ...
    self.limit = None
    self.order = None
    ...
```

I looseness/under-definedness of a bunch of these objects are partially my fault, as they were hastily ported over from `ndict`s to Python objects during a run of runtime performance improvements.
