Would it be valueable to implement lenses for dataclass in python3.7?

Currently this project only supports subscriptable data structure, meaning list, dict.
Would it make sense to extend these functionalities to python3.7 dataclasses? or attrs-based instances?

I'm not really sure what you're talking about. This library supports dataclasses:

import dataclasses
from lenses import lens

@dataclasses.dataclass
class Pair:
    left: int
    right: int

old_pair = Pair(1, 2)
new_pair = lens.left.set(3)(old_pair)
print(old_pair, new_pair)

My oversight. Thanks for pointing it out for me.
