get-array provides usage specifics of an <array> (created by new-array).
Use "length" clause to obtain its <length> (i.e. the number of elements stored in it), "hash-size" clause to obtain its <hash size> (i.e. the number of "buckets", or possible array codes in the underlying hash table).
"average-reads" clause will obtain in <reads> the average number of array-reads (i.e. how many string comparisons are needed on average to find a key) multiplied by 100 (so if an average number of reads was 1.5, it will be 150).
This information may be useful in determining the performance of a array, and whether resize-array is indicated.
