I'm still interested. I had my own crack at it with this although I haven't setup a test case for it:
command ArrayDiff @pArray1, at pArray2
-- use the list of keys so we make sure we support empty elements
put the keys of pArray1 into tKeys1
put the keys of pArray2 into tKeys2
-- any keys in pArray1 that aren't in pArray2 should stay
repeat for each line tKey in tKeys2
-- any keys in pArray2 that aren't in pArray1 should stay
if tKey is among the lines of tKeys1 then
if pArray2[tKey] = pArray1[tKey] then
delete variable pArray2[tKey]
delete variable pArray1[tKey]
-- if they are different and only one is an array then keep both
if pArray1[tKey] is an array and pArray2[tKey] is an array then
