+[@theteachr](https://github.com/theteachr) showed us the new game loop using `Seq.of_dispenser` making the game loop look like this.
+
+
+```ocaml
+let () =
+  let game =
+    [ "ocaml"; "reason"; "melange"; "dune" ]
+    |> List.map Player.make
+    |> Game.start
+  in
+  read_command
+  |> Seq.of_dispenser
+  |> Seq.filter_map Command.parse
+  |> Seq.scan Command.exec game
+  |> Seq.take_while Game.is_not_over
+  |> Seq.iter Tui.draw
+```
+
+**Highlights**
+
+We discussed,
+1. Possible use of GADTs for handling propert card transformations. You can find the git branch [here](https://github.com/theteachr/fortune/tree/gadt-property)
+2. use of `Seq.unfold`. [Code](https://github.com/theteachr/fortune/tree/unfold)
+3. Modular card transformations. [Code](https://github.com/theteachr/fortune/tree/property-modules)
