you would know, but that reference talks about why they are not the same as
NamedTuple.

if dataclasses *were*iterable, they almost certainly wouldn't iterate over
the values alone.

And NamesTuple was designed to BE tuples -- that is a drop in replacement
for tuples -- so they have the features they have partially for that reason.

And my toy code actually adds another decorator to make dataclasses
iterable, so it would be a completely optional feature.

All that being said, I'm not actually advocating doing this with
dataclasses -- I'm simply making the point that there are currretly two
ways to make custom class able to be passed in to the dict constructor --
do we need another?
