    Convert something to a NumPy dense array of the same shape.
    This is typically used a fallback for the various combining
    methods when there are lots of different array types that
    ``numpy.concatenate`` doesn't understand.

    Args:
        x:
            Some array-like object to be stored as a NumPy array.

    Returns:
        A NumPy array.
