> Lower quality editor/IDE integrations (when compared to TypeScript)

This is one of my favorite aspects of TypeScript, the first-class support it receives in Monaco Editor (part of VS Code) which is one of the reasons I also chose first-class TypeScript support when making Autumn, since I could embed Monaco right into it and get countless amazing IDE features for free.

> unfortunately, we had to change a very small amount of runtime code to fix some logic that TypeScript could not understand

Would be very curious what this is, I've only found maybe one or two things TypeScript could not understand, and they were already under active development in the Github repo.
