Review Comment:
OK, I've tried it out both ways, and see what `parent = e` does, but I think
it makes more sense the way it prints currently. What do you think?
The way it looks now:
```
Error in `open_dataset()`:
! Invalid: Error creating dataset. Could not read schema from 'file1.csv':
Could not open Parquet input source
'/tmp/RtmpLed3En/filebe14261f95ab2/5/file1.csv': Parquet magic bytes not found
in footer. Either the file is corrupted or this is not a parquet file.
/home/nic2/arrow/cpp/src/arrow/dataset/file_parquet.cc:338
GetReader(source, scan_options). Is this a 'parquet' file?
/home/nic2/arrow/cpp/src/arrow/dataset/discovery.cc:40
InspectSchemas(std::move(options))
/home/nic2/arrow/cpp/src/arrow/dataset/discovery.cc:262
Inspect(options.inspect_options)
ℹ Did you mean to specify a 'format' other than the default (parquet)?
```
With `parent = e`:
```

Run `rlang::last_error()` to see where the error occurred.
