I dunno. i think that is bogus. the trait (the 'is' stuff) must follow the declaration. traits affect variables and not values. also if @a was declared/used before this, i think that would be a compile time error to redeclare it. traits can only be used on a declaration and not on any general assignment. i don't think there is c style typecasting. you can assign to another type of var but its implementation has to decide if it likes the data you are giving it. it may allow it and internally do some 'casting'. and perl 'casting' usually would involve real munging of data or putting it in a different slot in the PMC or something. c's casting rarely changes the data (except for float/int) - it usually just changes the type.
