  - Further improve the consistency and expressiveness of Scala's language constructs.
 
 Corresponding to these goals, the language changes fall into seven categories:
-(1) Core constructs to strengthen foundations, (2) simplifications and (3) [restrictions](#restrictions), to make the language easier and safer to use, (4) dropped constructs to make the language smaller and more regular, (5) [changed constructs](#changes) to remove warts, and increase consistency and usability, (6) [new constructs](#new_constructs) to fill gaps and increase expressiveness, (7) a new, principled approach to metaprogramming that replaces [Scala 2 experimental macros](https://docs.scala-lang.org/overviews/macros/overview.html).
