Is the argument to generated createComment() calls ever used?

Generated code appears to use comments as anchors, but is the text of the comment ever used at runtime?

	var eachBlock_anchor = createComment( "#each allComments" );

Unless I'm mistaken only the comment object itself has to exist for Svelte functionality to work. Not including the comment text would save a few bytes in the bundle.

That certainly is true. There is also #3 which is a tracking bug to get rid of anchors completely if there is a static element that can be used.

Yeah, the names were just to make it easier to see what was going on when Svelte was first being developed — they've probably outlived their usefulness

I've just submitted a PR from a branch where I had been looking at this a little while ago. It makes all the anchors be empty comments.
