## Metaprogramming

The following constructs together aim to put metaprogramming in Scala on a new basis. So far, metaprogramming was achieved by a combination of macros and libraries such as [Shapeless](https://github.com/milessabin/shapeless) that were in turn based on some key macros. Current Scala 2 macro mechanisms are a thin veneer on top the current Scala 2 compiler, which makes them fragile and in many cases impossible to port to Scala 3.

It's worth noting that macros were never included in the [Scala 2 language specification](https://scala-lang.org/files/archive/spec/2.13/) and were so far made available only under an `-experimental` flag. This has not prevented their widespread usage.
