RelationalExpression : RelationalExpression >l ShiftExpression

Code: (Meta Ecma)

function evaluate(RelationalExpression > ShiftExpression) {
  var lref = evaluate(RelationalExpression);
  var lval = GetValue(lref);
  var rref = evaluate(ShiftExpression);
  var rval = GetValue(rref);
  var r = RelationalComparison(lval, rval, false); // 11.8.5

  return r;
}

Note that it gives leftFirst=false to RelationalComparison so it actually checks whether rval
