I spent a lot of time with it a few years back developing some documentation. I had actually forgotten the correct syntax and had to look it up. It was a lot of fun to use, though.

I should probably brush up on it a bit and maybe use it for some crap we have at work that's incomprehensible ("What calls what again? Does anyone know? And it's a bespoke language so there is no tooling to help? Shit.")
