Agree, that's fine. An `AttributeError` in this calling function might look weird, though, so you could have both.

This is in general a bad idea, since we are wanting to deal with large files, and we have random access capabilities.

It does, but this is an edge case of using fsspec for local files; these are normally passed as the filename.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,839823306

Unsure whether checking `hasattr` is better than just trying to read the object and catching an error - someone could implement a non-compliant `read` method, which would create other errors.

As a workaround, you could read it into BytesIO and pass the BytesIO instance:

```python
import fsspec
import xarray as xr
from io import BytesIO

of = fsspec.open(""example.nc"")
with of as f:
    xr.load_dataset(BytesIO(f.read()))
```

Also, [here's the link](https://github.com/pydata/xarray/blob/master/xarray/core/utils.py#L655) to the code referenced above.

Ideally xarray would work with `fsspec` or `pyfilesystem2` out of the box (to parse access URLs, for example).
I've had to fall back to using BytesIO buffers too many times. 😛 

Edit: You don't even need BytesIO, it works even with Bytes:

```python
import fsspec
import xarray as xr

of = fsspec.open(""example.nc"")
with of as f:
    xr.load_dataset(f.read())
