Interface SchemePair

All Known Implementing Classes:

Pair

public interface SchemePair

A SchemePair has two fields, first and rest (sometimes called car and cdr). SchemePairs are constructed using the factory method REPL.makeSchemePair(first,rest). There is a distinguished SchemePair REPL.EMPTY_PAIR, whose first and rest are itself. It represents the empty list.
