Hadn't planned on having a dispatch entry in the vtable--I wasn't thinking
it was really something worth localizing on a per-variable basis. Generally
I've been trying to keep control flow out of vtables. Vtables are for data
fetching/storing/manipulation. Opcodes are for control flow. Or so has gone
my thinking.
