Unused prop warning

[sharifzadesina]

How I am supposed to get rid of this warning?
The warning is because of removing the usage of the segment prop from the _layout component of the sapper.

https://github.com/sveltejs/sapper-template-webpack/blob/master/src/routes/_layout.svelte#L4

This is my whole code:

<script>
export let segment;
</script>

<main>
    <slot></slot>
</main>

I also tried to use <!-- svelte-ignore unused-export-let --> before the script tag but still no chance.

If I stop using segment prop I will get a warning in the browser saying:
<Layout> was created with unknown prop 'segment'

You can't, currently. There is an open issue for this #4652

As well as an issue on Sapper (where this issue belongs) to remove this prop sveltejs/sapper#824
