-- that is, you won't be able to tell which element came from which
original array, because the arrays were 'flattened' into one list. (Or,
put a little differently, Perl isn't Python.) You'll almost certainly
want to learn about references; instead of storing an array's elements
in another array, store a reference to the array. The documents perlref,
perllol, and perldsc should be helpful. In this example:

Now you can access the 'z' as $A[0]->[1]->[2] (or $A[0][1][2], if you


Hope this helps.
