    AExpression expression = (AExpression) visit(ctx.chain());
    final Operation operation;
    if (ctx.INCR() != null) {

    } else {
        throw location(ctx).createError(new IllegalStateException("Illegal tree structure."));
    }
    return new EAssignment(location(ctx), expression, null, false, true, operation);
}
