Here's a comparison of how distribute works for trees and how it works for lists:
# let tree_counter = TS.distribute (fun i -> S.(puts succ >> unit i)) t1 in
TS.run tree_counter 0;;
- (*
- : int T.tree option * S.store =
(Some
(T.Node
(T.Node (T.Leaf 2, T.Leaf 3),
T.Node (T.Leaf 5, T.Node (T.Leaf 7, T.Leaf 11)))),
5)
- *)
