Nit: could we move the this.isContextual(tt._using) inside this.startsUsing() (and maybe rename it to isUsing, similar to isLet)? Just because we are checking this.isContextual(tt._using) first every time we call this.startsUsing() anyway.

okay, we often call startsUsing in a big switch case so isContextual would introduce a duplicate using token check. But it probably has little impact on the performance.

startsAwaitUsing seems to have no reference anymore, let's remove it?
