>What would use suggest for the signature of a function like xr.ones?

Something like the following would work for me:

```python
def ones(shape, dims=None):
    """"""Create DataArray of ones with initialized coordinates

    Parameters
    ----------
    shape : tuple
        shape of the array
    dims : list of str, optional
        list of dimensions with same length as shape. The default will be
        dim_0, dim_1,...,etc
    coordinate_initializer : optional
        function which returns the appropriate coordinates. The signature for
        this function must be coordinate_initializer(dim, dim_length). The
        default is to initialize all the coordinates with
        ``np.arange(dim_length)``
    """"""
    pass
```
