Thanks. Your language looks like one I'd like to try. Getting rid of the outermost set of parens is a good idea; the fewer parens that you have to balance, the better. I haven't tried doing any serious programming in a whitespace-sensitive language. I've always found C very readable -- I think C hit a syntactic sweet spot. A lot of people must agree, judging by how many languages have copied C's style.
PS. The one whitespace-sensitive language I use often is make, if it counts. I like make's syntax.
