Type Projections... and why they work!
Let's dive into the world of Kotlin's type projections! We can't always use the `in` or `out` modifiers in a generic class, but don't sweat it - we can still get the generic subtypes we want! This video shows how you can use type projections to get generic subtyping - even for types that are in library code! In less than 9 minutes, you'll learn both how you can use them and why they work.
