Zero-dimensional inline arrays

[eschnett]

The standard specifies core/ndarray-1.0.0 that inline data for ndarray is given as YAML array (or array of array, etc.) This does not work for zero-dimensional arrays, i.e. scalars, which are most naturally represented as a scalar.

What does the standard intend here? Are zero-dimensional arrays not supported at all? Are they unsupported for inline data? If not, how should they be represented?

[drdavella]

If the intent is truly to store a scalar value, then an array should not be used at all, so the use of ndarray is not relevant. YAML natively supports float and integer scalar values, so there is no need for ndarray to handle these cases.
