Problem passing state data to js function in template

Help us to manage our issues by answering the following:

1. Describe your issue:

Hi there, I'm trying to do something which seems like it should be very straightforward. I'm attempting to pass some data to a javascript function in a riot template as below. In the Riot documentation it is stated that:

All template expressions are “just JavaScript™️”: <pre>{ JSON.stringify(props) }</pre>

So I am expecting that the below should function correctly as it is valid javascript.

<date-test>

  <p>Test date string: { state.test }</p>
  <p>Test transformed literal date string: { (new Date('2006-09-16T00:00:00Z')).toLocaleDateString() }</p>
  <p>Test transformed date string: { (new Date(state.test)).toLocaleDateString() }</p>

  <script>
    export default {
      state: {
        test: '2006-09-16T00:00:00Z'
      }
    }
  </script>

</date-test>

The first two <p> tags are rendered correctly but with the last one I'm encountering the following error reported in Chrome dev console

Uncaught (in promise) ReferenceError: state is not defined

Please note that I am not experienced in javascript - I write python, c/c++ for my day job - so it's possible that I'm doing something which is clearly wrong... Any guidance as to the correct way to do this would be much appreciated.

It's a compiler bug, I will check it asap
