I'm writing a real time strategy game and I'm using numeric ids on everything.
For example, each unit has an Id, and the command to attack another unit contains the target unit id. I keep all units in a (Dict UnitId Unit), so I can access each quickly. It's not as handy (or fast) as having pointers, but it is more robust: say the target unit is destroyed, the attacking unit will be left with Nothing to attack rather than a seg fault/reference error.
