Interesting.  Have you considered using normal string literals to name
blocks, rather than inventing new punctuation for the task?  I suspect
it may be more aesthetically pleasing, and it wouldn't break any
existing code, since a string literal can't legally follow 'do' or
'break' in Lua today.  (Just throwing the idea out there.  It's a
question of taste: just because I think the following fits more nicely
doesn't mean anyone else will.  :)

  while cond do
    do 'process_item'
      -- snip
      break 'process_item'
    end
  end
