 * This class represents a list of expressions used to
 * create closures. Example:
 * <code>
 * def foo = (1;2;;)
 * </code>
 * The right side is a ClosureListExpression consisting of
 * two ConstantExpressions for the values 1 and 2, and two
 * EmptyStatement entries. The ClosureListExpression defines a new 
 * variable scope. All created Closures share this scope.
