What happened?

https://docs.xarray.dev/en/stable/internals/how-to-add-new-backend.html#indexing-examples

I believe there's a typo in the BASIC indexing support example: ```python

shall support integers

backend_array._raw_indexing_method(1, 1) ```

Should be: ```python

shall support integers

backend_array._raw_indexing_method((1, 1)) ```

Suggestion of possible fixes: * Make sure it is a typo. * Create a valid custom MyBackendArray and initialize it. So it is easier to tell if it's a typo. * Add type hinting so mypy can easier catch these errors.

What did you expect to happen?

Minimal Complete Verifiable Example

No response

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.
