I'd be saving an index into the array for the related object so it could be directly referenced with a [index].method type reference, and that index would no longer be valid because once things are deleted they shift.

If I used iteration as your example shows, it would work, but it would also be slower.

The speed doesn't matter in this case as it will likely be at most a few hundred records, and perhaps 10 seconds of processing, and more typically dozens of records and a couple seconds processing max ... but it's the principle. :-)

I think I'll add support to Visual FreePro's design to allow this type of object to be saved in a table or cursor, with valid access existing only for the duration of the lifetime of the object.
