private void writeOutTypeTimes(BytecodeContext bc) throws TransformerException {
    Factory f = bc.getFactory();
    GeneratorAdapter adapter = bc.getAdapter();
    int times = adapter.newLocal(Types.INT_VALUE);
    ExprInt timesExpr = CastInt.toExprInt(getAttribute("times").getValue());
    ExpressionUtil.writeOutSilent(timesExpr, bc, Expression.MODE_VALUE);
    adapter.storeLocal(times);
    ForVisitor fiv = new ForVisitor();
