Description
Describe the problem
<script>
export let bar;
function foo(node, bar) {
bar = 123;
return {
update(bar) {},
destroy() {},
};
}
</script>
<div use:foo={bar}>
{bar}
</div>Currently this prints undefined. This makes recreating bind:group much harder.
Describe the proposed solution
Allow svelte/actions to update passed variables.
Alternatives considered
The passed object could be a reference.
