Scala 3 introduced many exciting new language features, and broke one old one. Scala 2's runtime reflection has been eliminated in favor of using compile-time macros to reflect on classes. This approach is a mixed blessing. If the type you want to reflect on is known at compile-time then performance of this new mechanism is very fast, however if you only know the reflected type at run-time you're basically out of luck. Well... not entirely out of luck. Scala 3 offers something called Tasty Inspection that can reflect on a run-time type but at a severe performance penalty, as this approach involves file IO to read your class' .tasty file. Tasty Inspection works, but it is orders of magnitude slower than Scala 2 run-time reflection.
