Review comment:
Since `strsplit()` is not a generic, this is the only way we can make it
usable in standard evaluation. But this will generate an additional message
when Arrow loads:
```
The following object is masked from ‘package:base’:
strsplit
```
I believe we want to avoid masking any more functions like this—is that
correct @nealrichardson?
The alternative is to make `strsplit()` usable only in dplyr verbs.
Non-standard evaluation allows us to do that without any masking. To do that,
you add a mapping here:
