There's no reason to have them, and that's just likely to be an
implementation issue with the current interpreter (it needs unset!
for unset words, and once you have that is pretty natural to have:
>> f: func  [return]
return unset!, being RETURN's argument unset; so they have
probably decided that empty blocks should have returned unset!

I was looking in your site to see what you intend for an illegal
error, but I wasn't able to find it.
