Yes, that's exactly what it comes down to.

A more automated way, though I'm not entirely sure if/how it would

Right! This would be by asigning "this" (the keyword) to the array at the
first location that's not yet used, right? We'd simply make the array quite
large to have headroom for later growth.

4. Add a static reset method, that runs the object reset method from

No, as far as I understand it now that would work fine and it's actually
quite clever and clean, I think. I think I'll use this method, it will also
make what I'm doing now far easier to extend without having to manually keep
house in some arbitrary spot. I don't like it when things that are that
important to the overall stability have no clear place in the program.
