ในรุ่นนี้ไม่มีข้อความแสดงข้อผิดพลาดโดยละเอียดและเอาต์พุตเป็นพื้นฐานมากกว่า การเปลี่ยนแปลงที่สำคัญถูกแทนที่Either String aด้วยMaybe aและเนื่องจากพวกเขาทั้งสอง monads นี่คือทำได้โดยเพียงแค่การแลกเปลี่ยนRight aกับJust aและกับLeft StringNothing

การทดสอบ
ด้วยภาพหน้าจอเพื่อป้องกันการไหม้ของดวงตา
$ printf "232425140504032627" | ./rve
$ printf "2324" | ./rve
$ printf "1" | ./rve
invalid coordinates string
$ printf "24" | ./rve
wrong move (2,4).
คือเป็นไปได้ที่จะได้รับimpossible move (x,y)เมื่อคุณใช้ innardics (ฟังก์ชั่นจากอวัยวะภายในของโปรแกรมและการที่คุณไม่ควรใช้) x/y is out of boundsและ
