[OriginalDemo](modules/demos/src/main/scala/demos/OriginalDemo.scala) - The original demo from [stepwise](https://share.unison-lang.org/@pchiusano/stepwise), shown in the video. Translated to Scala.\n```bash\nscala-cli https://raw.githubusercontent.com/marcinzh/daae/master/modules/demos/src/main/scala/demos/OriginalDemo.scala  \n```\n\n\n2. [TreeWalk](modules/demos/src/main/scala/demos/TreeWalk.scala) - Using multiple effects. Demonstrates that when `Debug` goes back in time, local state (e.g. `Reader`, `State`, `Writer`) gets restored as well.\n```bash\nscala-cli https://raw.githubusercontent.com/marcinzh/daae/master/modules/demos/src/main/scala/demos/TreeWalk.scala\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarcinzh%2Fdaae","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmarcinzh%2Fdaae","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarcinzh%2Fdaae/lists"}
