On second thought I don't care that much.

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.
