@jayqi Let me know if you have thoughts on putting this functionality in cloudpathlib. Now that it is implemented, I could also see this making sense in the pandas-path package rather than here. I don't feel strongly either way.

[jayqi]

Yeah, I guess it could go either way:

---

pip install cloudpathlib[s3]
pip install pandas-path

from cloudpathlib.pandas import cloud

---

pip install pandas-path[s3]

from pandas_path import cloud

Now that I've seen it, I guess the interface looks cleaner to have this live in pandas-path.

[jayqi]

@pjbull the more I've thought about this one, the more that I think having this as an extension within pandas_path makes more sense than including it in cloudpathlib.
