I suggest you keep in mind what Miles Parker said at SwarmFest: 

When you are tempted to start looking for magic compiler flags to
unroll loops, etc. (or in this case move to lower level data
structures), it's time to take a coffee break and think more about the
problem.  Yes you will save a little bit of memory using a C array
instead of a Swarm collections Array, but you have to balance the
comprimised clarity of your model against the performance increase,
which in this case won't be more than a few percent, I expect.

Please don't take this as a flame, but here is some more advice: 
if you can't take the time to read the C manual to learn about a (simple)
feature you think *might* be useful, then don't use that feature
*even* if someone on this list is so kind as to show you a prototype
of its use.  That's a reckless and insidious kind of programming.

Always have the goal of understanding what you are doing.
