 jsint.Pair
| Pair | | public class Pair implements java.io.Serializable,jscheme.SchemePair(Code) | | A Pair has two fields, first and rest (sometimes called car and cdr).
The empty list is represented as a Pair, with both fields empty.
(In Scheme it is an error to ask access those fields, but we don't complain.)
