I maintain some numerical methods / stats code and am eager for a DocC story on this topic.
At the moment I rely heavily on what you term Unicode math in my comments. It’s important to me that equations be interpretable inline as well as in documentation. Once the math gets even moderately complicated equations inline in the comments can make a huge difference in code readability. For my current audience Latex would probably do as well as Unicode for inline readability.
I am not knowledgeable on the topic of producing the most useful documentation output from this input but wanted to express my preference for inline readability.
Thank you for working on this!
