[Milan-pm] comparing 2 lists

[Lally Blue]

are the 2 arrays items in the same order?
in the reference it says:
"Internally the comparator compares the two arrays by using join to turn
both arrays into strings and comparing the strings using eq."
so I guess that if the first array has 1,2,3,4,5 and the second one
5,4,3,2,1 the Array::Compare returns false...
is this what you mean?
