Hi, as I understood, a lot of people seem to have problems with this proposal, since arrays and strings could (and maybe should) behave the same. The main problem arises from the ambiguity for $array[-1] for arrays. But this is easily solvable: just introduce a slice operator. $array[:-1] and the ambiguity is gone. -- Cheers Jannik Zschiesche
