I'm not sure there ever was a "proposal" per se, but:

ntuple(x=a, y=b)

had better be a different type than:

ntuple(y=b, x=a)

but first we need to decide if we want an easy way to make an
namedtuple-like object or a SimpleNemaspace-like object....

but if you are going to allow indexing by integer, then order needs to be
part of the definition.
