- Explicit naming of samplers: from `grid`, `random` to `grid_sampler`, `randm_sampler` etc. - Explain or eliminate `**kwargs` in public API e.g. `grid` documentation says it accepts `kwargs` but what are the expected arguments? - Unify ways to execute block. Currently there are multiple ways to do the same thing i.e. with `experiment_data.run` or with `Block.call` etc. - `Datagenerator` block is confusing since the `execute` method uses `self.experiment_sample` without very providing it explicitly.
