I’ve compared the two a while ago, seems to me like slightly different takes around the same core ideas. It’s true that a couple of things in Ansel feel more natural, but it’s not much, and it’s probably not worth the risk (AFAICT the bus factor is one, compat with DT isn’t a goal).
That’s frankly mind blowing. About as much as parallel-collections gaining support for scala-native in the recent days, with the PR not even touching a single line of code (only through build configuration). The scala ecosystem is way under-appreciated :-)
