For NumPy Arrays, item is a convenience method that returns a scalar from a NumPy array with a single value. If the NumPy array does not have a single value, it errors out. Would be nice to have a similar method for Dask Arrays.

Should it return a computed Python scalar or a dask.delayed object?

IMHO it should be some lazy object (ideally a Dask Array). It's pretty easy to compute if one wants to.
