+- Strong typing in combination with excellent inference enables mechanisms like [contextual abstraction]({{ site.scala3ref }}/contextual/motivation.html) that allows you to omit boilerplate code. Often, this boilerplate code can be inferred by the compiler, based on type definitions and a given context (e.g. method arguments for implicit parameters).

 ### A pure OOP language
 
 Scala is a _pure_ object-oriented programming (OOP) language.
-Every variable is an object, and every “operator” is a method.
+Every variable is an object and every “operator” is a method.
 
 In Scala, all types inherit from a top-level class `Any`, whose immediate children are `AnyVal` (_value types_, such as `Int` and `Boolean`) and `AnyRef` (_reference types_, as in Java).
 This means that the Java distinction between primitive types and boxed types (e.g. `int` vs. `Integer`) isn’t present in Scala.
 Boxing and unboxing is completely transparent to the user.

-Add the “types hierarchy” image here?
+- AnyRef above is wrong in case of strict null checking, no? On the other hand, maybe too much information to state this here
+- probably not worth to mention (too advanced at this point) there is AnyKind
