I've been writing some solutions to Advent Of Code in KAP in order to demonstrate how their language works. It's also useful for me to actually solve some real problems with it. When designing a language it's easy to get stuck in theory rather than paying attention to how it can actually be used.
Here's the code: https://github.com/lokedhs/array/blob/master/demo/advent-of-code.kap
I'll be happy to answer any questions you may have.
