No, Dave's saying that all the memory for all the items in the list will get
allocated when you Dim the array - and so if you have each item in the list
containing 1000 longs, you will be allocating 1000 (for the number of items in
the list) * 4 (sizeof.l) * 1000 (number of longs in each item of the list)
which gives 4000000 bytes (3.8Mb ish).

Which we all know isn't always the case with Blitz :)
