Break or fixed width delimiters are different than enclosing delimiters. There's no longer any parens matching. And not 2 things to keep track of (notice how Bel is both using parens but also following a whitespace convention for readability--that is then stripped and ignored by the compiler). And also, your program is never in a syntactic error state--such things no longer exist. Semantic errors are still there, of course, but a whole class of errors goes puff.
