Short: I've just pushed a fix. Long: The student languages disallow reading "dotted" pairs like '(1 . 2) which the Web server uses when encoding continuation identifiers into URLs. This restriction is in effect for the dynamic extent of the evaluation of a student program. The fix is to explicitly ensure that this option is on in the continuation URL decoder.
