What are some advanced concepts in Haskell type classes?
Advanced concepts in Haskell type classes include associated types, multi-parameter type classes, and functional dependencies.
Can you explain associated types with an example?
Sure! Associated types allow you to define a type that is associated with a type class. For example, in a type class for a container, you might have an associated type for the element type.
How do multi-parameter type classes differ from regular type classes?
Multi-parameter type classes allow you to define a type class that takes more than one type parameter, enabling more complex relationships between types.
What are functional dependencies and why are they useful?
Functional dependencies specify a relationship between type parameters in multi-parameter type classes, helping the compiler resolve ambiguities.
