This is wasteful if you're not planning to use every ID in this

Of course, if you plan to use most of the array, then the AA
may wind up using more memory than the array. So it depends on
your use case.

yes, I was thinking this over as I was waking up this morning,
and thought... what the hell am I doing generating all those
numbers that might never get used.
better to do:
const int iotaStartNum = 100_000_000;
int[] idArray = iota(startiotaStartNum, iotaStartNum +
recordsNeeded).array;
