@ChuanqiXu9, I updated the check like you suggested, and it should look much nicer now. The only caveat is that the `children()` call isn't going to cover the implicit destructor call in a `CXXBindTemporaryExpr`. That pattern matching case is here to stay and likely there are many other types implicit calls that make this analysis unsound (See https://eel.is/c++draft/except.spec#6). In reality none of them can reach here though.
