Code Sample, a copy-pastable example if possible

python ds = xarray.open_dataset(...) da = ds.variables['...'] da.<tab>

Problem description

This starts reading data. I don't know why. I'm using XArray against a FUSE system that is both expensive (it's targetting Google Cloud Storage) and also has logging. I can see that auto-completion immediately starts a lot of file reading on the file system.
