When ``name`` is a string, return the item of the given name. Otherwise, this

Label-based indexing is only possible when all items have a coordinate for the
indexed dimension.

Advanced indexing comprises integer-array indexing and boolean-variable

the item shapes are inconsistent for the indexed dimensions, provided that all
