Glad that you liked it :)

What you’re saying reminds me a lot of a talk I listened to some time ago, https://www.youtube.com/watch?v=8Ab3ArE8W3s. If you can spare 45 minutes, it’s a really good listen. Particularly the debugging section should be interesting for you, but I’m not sure I’d recommend skipping ahead.

The talk is more on a conceptual level but there are some really good concrete examples near the end. Maybe listening can give you a good starting point on what to look for.
