Hey abyaly, pay no attention to Nums. It's my fault really. He's a good monkey, but he gets cranky when he's hungry. I'm supposed to feed him when PY is away, but I forgot....
The refvars that do exist are mostly just a convienent shortcut to using the memloc/memval pair. We could add refvars for everything, but that would be a lot of work and double the size of the bot's memory array...
