After looking around at the alternatives, I decided I should simply update my 2005-era gherkin module, and make it an easy installable package. When the cheeseshop comes back online I'll do the upload.
I've added support for sets, and complex numbers. I even tried to make it faster, but ended up in defeat. I had forgotten how much time I had already spent optimizing the thing... My 2007 brain could not best my 2005 brain... hmmm must be getting old.
In other news, the new Super Ajax-ified Media Widget (Scouta Play) went live earlier this week on the front page of scouta.com. It doesn't use gherkin, it uses json. :-) Band of None have also released a new tune, Hoffburger.
