Scala metaprogramming, reflection beyond mirrors by

The presentation looks at the two main approaches available in Scala 3 — mirrors and macros — and argues that while mirrors are common, they often lead to awkward code, unsafe casts, and poor runtime output. In contrast, macros give developers type safety, composability, and full control over the code they generate.
