Make bind:group work the same as bind:value={get, set}.

[thebjorn]

Describe the problem

The syntax for bind:group is different from the syntax for bind:value with a get, set tuple for no apparent reason...?

For the bind:group case you need to create a facade object which get/sets a name:

<script>
    let val = $state("2");
    const facade = {
      get val() { return val; },
      set val(v) { val = v; },
    };
</script>

<label><input type="radio" value="1" bind:group={facade.val}> one</label>
<label><input type="radio" value="2" bind:group={facade.val}> two</label>

<input bind:value={() => val, v => val = v}>

Describe the proposed solution

It would be great if bind:group={() => val, v = > val = v} would work the same way as it does for bind: value.

It would be even better if the tuple could be passed as a value, i.e. without being destructured:

<input type="radio" bind:group={form_context.get_accessor('name')} ...>
