Ceylon은 튜플에 일부 함수를 적용 할 수 없습니까?

이 코드의 잘못된 점은 무엇입니까?Ceylon은 튜플에 일부 함수를 적용 할 수 없습니까?

value x = [[1, Color(0)]]; 

//Exception thrown here 
value y = x.map(([Integer, Color] elem) => "``elem[0]`` -> ``elem[1]``");

... 마지막 줄이로 대체 할 수있다 :

value y = { for(elem in x) "``elem[0]`` -> ``elem[1]``" };

... 나는이 잘 실행해야합니다 생각하지만, 두 경우 모두 내가이 오류를 얻을 :

반복 가능한 구문을 사용합니다. 값 x = [[1, 색상 (0)]];'대신에 값 x = {[1, 색상 (0)]};을 사용하여 문제를 해결하지만 여전히 . – Renato

실론 전용 코드로 시도한이 문제는 사라집니다 ... Java interop 문제가있는 것 같습니다 (색상이 java.awt.Color를 참조합니다). – Renato
