> {{Array.deep}} no longer exists in scala 2.13. It is used sometimes in the
> code to compare the elements of two arrays, as {{==}} tests only reference
> equality. However {{sameElements}} is better anyway. In cases involving
> nested arrays we might have to manually compare the sub-arrays though.
