Hello everybody!
The potential for a `SORT_NATURAL` flag also came to mind as another
useful addition, but I believe `SORT_STRICT` is the more critical
feature to discuss first.
I know I find array_unique generally useless due to its insistence on
stringifying everything for comparison.
```
$uniques = [];
foreach($source_array as $a) {
if(!in_array($a, $uniques, true)) {
$uniques[] = $a;
}
}
```
I seem to recall part of the issue is that array_unique works by sorting
its elements so that "equal" values are adjacent. I know this would be
done on O(n log(n)) vs. O(n^2) grounds, but that could be addressed at
least in part by a smarter sort criterion that sorts by type/class (in
some arbitrary order) before sorting by value. For uncomparable types
(i.e., instances of most classes) this would be by object ID, because we
don't _actually_ care about ordering.
