[wp-testers] get_categories hierarchical not working

[Nathan Rice]

Then perhaps hierarchical means something different in get_categories than
it does in get_posts. It was my understanding that the hierarchical argument
was a sorting mechanism, returning child categories (and other descendants)
directly after their parents. For example:

(array)
Parent
Child
Grandchild
Child 2
Another Parent
Child
Yet Another Parent

That's what the argument does for get_pages at least. The Codex page
indicates that as well:
"Display sub-categories as inner list items (below the parent list item) or
inline."

@Demetris

Here's the exact call I'm making:
$categories = get_categories('hide_empty=0&hierarchical=1');
