Bonsai_bench_scenario.Scenariotype ('input, 'action) t = {initial : 'input;test_name : string;interaction : 'input Input.t -> 'action Interaction.t;}A Scenario.t is a useful pattern for specifying the inputs and interactions for a benchmark or interaction Computation_report test. It allows instantiating a Var.t for the test locally, so it gets GCed between runs.
