Thanks, Pierre.
Sumti that are attached to a selbri in a place that is undefined in jbovlaste, get a "context dependend" meaning. It would be very stretchy to interpret the tunlo2 differently from "what is being swallowed". That said, I think that tunlo2 should have been defined this way since the beginning :)
About lo/le, I have the habit of switching to {le} when I talk about a specific thing that might have been introduced with {lo}.
After having said {lo labno noi ....} any time I write {le labno} I mean *that* wolf. If I wrote {lo labno} I might mean another wolf.
