Review comment:
Yes, that's a good alternative, but in this case we'd have to deal with
`throws Exception` in its signature.
The client side would look like this then:
```
try {
targetFile.deleter().call();
} catch (Exception e) {
throw new IOException("Failed to delete file", e);
}
```
Is there a different `Callable` interface without checked `Exception`
declaration?
