Yesterday I was speaking with my kids about evolution, so I wrote a one-hour project to see how quickly advantages can spread. And took advantage of Marginalia to make it readable.
This is the kind of toy project - IMHO - where Clojure really shines.
Yes Marginalia helps a lot in making readable docs (so I have an excuse to read again my function comments). It’s rather weak in other respects, eg cross-indexing.
