@-prefixed literals for collections are definitely welcome (I won't miss those nested 'dictionaryWith...' calls for sure). Anyone know how the []-access will work? Is this going to be a special case for NSArray/NSDictionary synthesized in by the compiler, or is there going to be runtime support for a []-operator message a la Ruby, or maybe something related to key-value coding? I hope this is done coherently, anyway. I worry that too many special cases to overcome problems like verbose collection access could snowball.
