Is this documented anywhere? I was expecting to see an option in https://www.docz.site/documentation/components-api#playground

seems it is not working in 0.13

it does work if you wrap it in a closure:

<Playground>
  {() => {
    const someVar = 'value'
    return <MyComponent example={someVar} />
  }}
</Playground>

gives you an editable field for that code. Probably should be documented.
