Nevow Stan, which Breve is inspired by, had a feature called "patterns". More or less, this feature let you repeat blocks of the DOM, substituting values into the repeated block.

I've been wanting to add a similar feature to Breve, but didn't feel the Stan way of doing it fit well (it could be a little hard to understand).

Anyway, I think I finally found a couple of approaches that I like (and implemented one of them).

If you're interested, I discuss it here.
