this isn't a bug report - but something you've just reminded me of.
I was looking at an import export thing over the weekend. By coincidence, i had to nick the PMA one for something at work last week, which was a head start.
Anyhow ... i prodded it for a while with a view to beehive, but all of them use loops - which suprised me, and which i believe you advised was a bad idea. And i believe you.
So dead end.
