Comment (by goldfire):

 A variable could conceivably be mentioned in both `ftkv_kis` and
 `ftkv_tys`, so naive appending might cause duplication. I don't think
 order is significant. If it turns out to be somewhere, we could always use
 the source locations to restore order.

 Agreed with Simon's plan in comment:10.
