Would you happen to have any feel for / comparative docs around how Java does all this? Java has had compile-time metaprogramming for a very long time, integrated with IDEs (well. eclipse), the type system, hot reloading, AOT, etc. It seems like one worth looking closely at, since most are rather simple in comparison (e.g. a huge amount are syntax-based and don't have in-progress type information).

Though it would not surprise me at all if it was considered too slow to adopt. I don't remember compile-time performance issues with it when I did Java work, but I was definitely not paying close attention, and the ecosystem strongly prefers runtime shenanigans in general.
