Fixed a pretty bad error in isNullable logic, I must have been tired. Also, edited grammer to support a[n].b, which was previously done with wrong operator precedence so that that construction was illegal. vector.krak still doesn't quite parse, but that's because of some error with if (!name) which I will fix later. Bedtime.
