Those functions should not return a string when they receive a
non-empty-string in input.
The following example is expected to work:
```php
<?php
/**
* @param non-empty-string $i
*/
function takesNonEmptyString(string $i): void {
echo $i;
}
takesNonEmptyString(bin2hex("a"));
takesNonEmptyString(base64_encode("a"));
```
