What are advanced types in Haskell?
Advanced types in Haskell include features like type families, GADTs, and existential types, which enhance type safety.
Can you explain type families with an example?
Sure! Type families allow you to define functions at the type level. For instance, you can create a type family that maps types to their corresponding numeric types.
What are GADTs and how do they differ from regular data types?
GADTs, or Generalized Algebraic Data Types, allow you to specify the type of constructors more precisely, enabling more expressive type systems.
How do existential types work in Haskell?
Existential types allow you to hide type information, enabling you to work with different types under a common interface.
