add C<> tags, fix typos, fix out-of-date \$args to |$args, use Callable (not Code or others) for the role, change .wrap to return a cookie object to unwrap, remove the only use of := that wasn't in a declaration (hoping for single-assign semantics) and show regular assignment for Routine to replace its "do" property without changing the Routine object's identity.
