FWIW, I was looking into something similar but didn't proceed because it would break eval(repr(s)) == s as the constructor signature 
wants all the args in a tuple and won't accept keywords.  Still, I think what you did is a nice improvement.

Here's a couple more if you want to proceed down that path:

1. Have structseq subclass from PyTupleObject so that isinstance(s, tuple) returns True.  This makes the object usable whenever 
tuples are needed.

2. Add _fields, _asdict, and _replace to match the API in collections.namedtuple().  The _fields tuple should only include the 
visible positional fields while _asdict() and _replace() should include all of the fields whether visible or accessible only by 
attribute access.

Thanks for the nice work.
