I'd be totally OK with the magic in something like Spring or Ruby on Rails is another good example if it had code I could inspect when things go wrong. That is really my one and only complaint that I have about "magic".

I currently find myself playing around now a lot with Dart which has a lot of the same convenience and just handles it via code generation rather than dynamic magic at runtime. For me at least, it's a really nice trade off. It also for the record has fully sound null safety which is something I have only ever seen in Swift previously but is a real pleasure to work with.

I guess in the Java world you have options like Quarkus that also give you a similar kind of experience.
