Looking at 
<https://spk121.github.io/guile-gi/Function-Parameters-Arity-and-Return-Values.html>,
on the Scheme level the output parameters would be converted to return values,
so the API would be

(receive (selected iter model)
  (tree-selection:get-selected selection) ; or 
  [do things with iter and iter and model])

Doesn't seem to work though -- looking at
(generic-function-methods tree-selection:get-selected), Guile-GI incorrectly
doesn't convert it to a return value or something?

Greetings,
Maxime.
