module 'xarray.core' has no attribute 'rolling'

[davidbrochart]

What happened?

There used to be a xarray.core.rolling, and the documentation suggests it still exists, but with xarray-2022.6.0 I get: module xarray.core has no attribute rolling.
It works with xarray-2022.3.0.

What did you expect to happen?

Shouldn't we be able to access xarray.core.rolling?

Minimal Complete Verifiable Example

import xarray as xr

xr.core.rolling
# Traceback (most recent call last):
#   File "<stdin>", line 1, in <module>
# AttributeError: module 'xarray.core' has no attribute 'rolling'

MVCE confirmation

• Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
• Complete example — the example is self-contained, including all data and the text of any traceback.
• Verifiable example — the example copy & pastes into an IPython prompt or Binder notebook, returning the result.
• New issue — a search of GitHub Issues suggests this is not a duplicate.

Those modules are no longer imported by default, so you will have to explicitly import them yourself to access them:

import xarray as xr
import xarray.core.rolling

xr.core.rolling

(the changelog lists this under "Internal changes")

Thanks @keewis !
