Russ Cox (who worked together with Rob Pike on Go for a long time) solved several of last year's Advent of Code puzzles using Ivy. Here's a YouTube playlist where he has recorded himself doing so: https://youtube.com/playlist?list=PLrwpzH1_9ufMLOB6BAdzO08Qx.... I don't think he's solving the problems for the first time in these videos, instead merely demonstrating how they can be solved using Ivy.
