Hi Serhiy,
Thanks! Now, I am feeling confused. On the one hand, it's already been
tried 10 years ago. On the other hand, obviously people do wish to have it.
I'm going to send a PR In GitHub. Let's see if a new PR with some
documentation can be appreciated.

Unless I'm missing something, that doesn't have the memory improvement that

Actually, IMO in this case it would be more useful and fitting to use
namedtuples rather than dataclasses, since CSV rows are naturally
tuple
Hi Steve,
Thanks for your reply. While dataclass provide a cleaner API than DictRow
(you can access `row.id` instead of `row["id"]`).
However, dataclass still use the built in `__dict__` instead of
`__slots__`.
```
>>> @dataclass
... class InventoryItem:
... '''Class for keeping track of an i
If using a dictionary but still requiring attribute access, techniques such
as those used at https://github.com/holdenweb/hw can be used to simply
client code.
Kind regards,

Since 3.7 it may be that dataclasses offer a cleaner implementation of the
functionality you suggest. It shouldn't be too difficult to produce code
that uses dataclasses in 3.7+ but falls back to namedtuples when necessary.
You may wish to consider such an implementation strategy.
Best wishes,
