It’s a specification for a tiny 1977 programming language called PCF, with the intention that people can write implementations in different languages and then compare them.

It’s inspired by [https://github.com/gothinkster/realworld](https://github.com/gothinkster/realworld), but since I’m not that interested in HTTP APIs I wanted to have something similar for another domain.

I might do another one later for either a tiny MMORPG or chat app, that would be especially fun since it would lend itself well to benchmarking.
