Coming from many years in common lisp, I often wonder this. With things like coffeescript I felt the syntax didn't add much, but you've got the chance to do something great...add macros!! Rust is a good example of grafting macros onto an existing language, and the JS syntax is even simpler than rust, so why has nobody done it in any of the compile-to-JS languages? Seems like a waste of an opportunity.
