[wp-hackers] Weird behavior (maybe a "bug") in get_term_link()

[Davit Barbakadze]

Wow, that's kinda twisted.

It never came to my mind though that slug can be numerical. Yeah...
but that's even more confusing...

Hmm... I think this can potentially bring more awkward moments, once
people start to use this intensively with custom taxonomies. Or is
there some kind of replacement already?
