How do Haskell type classes affect performance?

Haskell type classes can impact performance in various ways, such as through code bloat and inlining. Would you like to know more about specific examples?

Yes, can you explain code bloat in this context?

Code bloat occurs when multiple instances of a type class are generated for different types, leading to larger binaries. This can slow down compilation and increase memory usage.

Are there ways to mitigate code bloat?

Yes, you can use techniques like using newtype wrappers or limiting the number of instances to reduce code bloat.

What about performance trade-offs with type classes?

Type classes can introduce runtime overhead due to dynamic dispatch, but they also provide flexibility and code reuse, which can be beneficial in many cases.
