Cannot see how it's shorter and more readable than a formal grammar + AST production rules. Given that the class syntax is very bloated (unlike, say, ML ADT constructors), there is no chance a language grammar will be compact and comprehensible at a single glance. Disclaimer: of course I'm biased, I'd oppose anything with the word "class" in it.
