Can you add optional _outer_ tags in svelte conditional statement?

Is it possible to use a conditional statement to wrap inner content with an optional outer element?

Here is an example of what I want to do in valid Svelte:

<script>
  export let needs_div_wrapper;
</script>

{#if needs_div_wrapper}
  <div>
    <a>My static content!</a>
  </div>
{:else}
  <a>My static content!</a>
{/if}

And here is an example in non-valid Svelte that demonstrates what I want to do:

...

{#if needs_div_wrapper}
  <div>
{/if}
    <a>My static content!</a>
{#if needs_div_wrapper}
  </div>
{:else}

EDIT: Just for clarity, I'm trying to accomplish this without a new component for the inner content.

No, it is not possible.

A wrapper component is probably the cleanest you can do in this case, to avoid repeating potentially non trivial markup in the "parent" component.

As I understand it, you've already found this solution, but for the record here's what I mean:

DivWrapper.svelte

<script>
  export let wrap = false
</script>
{#if wrap}
  <div {...$$restProps}>
    <slot />
  </div>
{:else}
  <slot />
{/if}

App.svelte

<script>
  import DivWrapper from './DivWrapper.svelte'

  export let needs_div_wrapper;
</script>

<DivWrapper wrap={needs_div_wrapper}>
  <a>My static content!</a>
</DivWrapper>
