Module Incremental_lib__.Incremental.Make.Let_syntax

This Let_syntax allows you to write expressions like

        let open Incr.Let_syntax in
        let%map_open some_incr = watch some_variable
        and another_incr = ...
        and ...
        in
        ...expression involving some_incr, another_incr, etc...

Note that this is less efficient than using map3, map4, etc., as the latter produces fewer intermediate nodes.
