Not sure I like that better. It's an open-ended sequence of homogeneous
types. What's the advantage of a tuple? I don't want to blindly follow
existing APIs.
So people don't modify it, but consenting adults would say "don't do
that". I currently return a new tuple in each call to fields(), but in
the future I might return the same one every time (per class).
I really don't care so much. The only reason I made any change was
because the implementation was returning an OrderedDict, so I was
changing the tests anyway. I'm happy to change it back to a list, based
on the convention of homogeneous types being in a list.

I've made a minor change: the return type of fields() is now a
tuple, it was a list.

I've pushed another version of PEP 557. The only difference is
changing the default value of "order" to False instead of True.
This matches regular classes: instances can be tested for
equality, but are unordered.

I've updated the implementation on PyPI to reflect this change:
