another interesting feature would be some sort of "find" function
for arrays... for instance :
    put "myText" into T[5,8]
    find "myText" in T  ----> would return "5,8"
                                             or a list of found chunks
if it is in more
                                             than 1 array cell

I know this can be emulated using the "combine" function, and then
itemoffset of lineoffset, but it would be more elegant (and probably
faster).
And I don't think this means a major rewriting...
