  I'd consider the Associative Array with any numeric key as a 
sparse array; Course like that you wouldn't get them in any 
particular order... And most of the time you wouldn't need to.

  I've found all kinds of interesting uses for numeric based AA's, 
one of them is one of my examples of an expanding prime 
number-generating range, another could be for a COW 
(Copy-on-write) based array; Reminds me I'll write a struct for 
one if there isn't one yet.
