Also looks a lot like Ruby's amrita.

I was just looking around for a perl version of that the other day, so I'm glad you're writing one.

Are you aware of Amrita? Do you have any design goals about compatability? It would be kind of cool if the same template could work with ruby or perl code.

I've not followed the amrita dev closely, but I saw some remarks that they had re-worked things a bit after the the first version, so there might be some useful lessons learned to pick up.

IMHO, it should go in HTML. It would be useful for manipulating HTML, irrespective of whether those pages were to be served via HTTP or made available to 'the web'. (Splitting hairs, I know, but hey.)

I'd also call it Atirma or something like that, personally :-)
