Feature Request: Retry on Error

See original GitHub issue

For example,

async function main (): Promise<void> {
  await new Listr([
      task: (ctx, task) => {       // line #4
        return (
          execa.command(`xyz -y`)
               .then(()=> // do something)
               .catch((err: any) => {
                 // e.g. the user doesn't have `xyz` installed or accessible
                 if (err.code === 'ENOENT') {
                   npm install xyz // <---- address specific error
                   task.retry(1)   // <---- rerun the current task, e.g. the
                                   //       task starting on line 4 of this
                                   //       example;
                                   //       to avoid infinite loops, pass a
                                   //       maximum number of retries, e.g. `1`;
                                   //       should probably default to `1`
    ], {}

Good to know that the strict null checks may show up as undefined initially. 👍

The other type errors were showing up in my IDE (VS Code) because I hadn’t enabled the TypeScript extension (TypeScript Hero). 😳

Yeah with scrict null checks that is possible because that item is initially undefined.
