I do! Pretty sad that IronPython isn’t a thing anymore, especially now that I’ve actually had to learn Python for machine-learning related reasons. At least .net did get the dynamic data type out of its brief interest in these.
IronScheme[0]! I was pretty happy to be able to expose async-await in a neat little library[1]. I wonder if it's in use anywhere. I didn't get to use it in the project I was working on at the time.
