without a __toString() method that always produces different strings for
different objects, array_unique() can't be used to deduplicate an array
of objects - which I find myself wanting to do on a fairly regular basis.
```
$uniques = array_values(array_combine(array_map(spl_object_id(...),
$source_array), $source_array));
```
