in reply to array of arrays

let me explain more. what i need is like this:
@array=({hashkey => [@otherarray, @etc]}); $array[0]{hashkey}[0]=@otherarray - this doesn't work either
What i'm doing is sort of like a linked list, except it can point to many different elements which are all arrays. I need to extract the different values and then do some stuff with those arrays.
