表达式执行结果解释

```
NAME_EQ(passengerName,aiName)
&&
(
(
flightWay=='S'
&& aiCountry==GET_PROP(LAST_SEQUENCE(flights),'arrivalCountryCode')

我有一个比较复杂 的 表达式，目前只能拿到执行结果 True/False ， 除了 True/False ，如何才能拿到是哪些 表达式执行失败的

The issue provides only a complex expression and does not name a source file, test, or evaluator entry point. Start by locating the API that currently returns the boolean result, then clarify how failed subexpressions should be represented and verify the expected behavior with a test covering the nested && and || expression.
