We do this quite a bit in the Arrow<->Parquet bridge if IIUC. There are
macros defined like this:
```
#define BEGIN_PARQUET_CATCH_EXCEPTIONS try {
#define END_PARQUET_CATCH_EXCEPTIONS \
} \
catch (const ::parquet::ParquetStatusException& e) { \
return e.status(); \
} \
catch (const ::parquet::ParquetException& e) { \
return ::arrow::Status::IOError(e.what()); \
}
```
That being said, I'm not particularly fond of macros, but it works.
