Disagreed. I've really come to enjoy parens-less coding, though I know  
others don't like it. But today both camps can write in their preferred  
style and write libraries for each other. Either deciding on an opt-in  
(@property) or opt-out(@!property) basis seems likely to A) kill the other  
programming style or B) lead to a bunch of synaptic load on the programmer  
as they try to remember which style each class uses.
