What are the best practices for using the Haskell async library?

When using the Haskell async library, it's important to manage your threads effectively. Always ensure that you handle exceptions properly and use wait to retrieve results safely.

Can you explain how to handle exceptions in async operations?

Certainly! You can use Async's waitCatch function, which returns an Either type. This allows you to handle both success and failure cases gracefully.

What about resource management? Any tips?

Yes, make sure to use withAsync to ensure that resources are cleaned up properly after the async operation completes. This helps prevent resource leaks.

Are there any performance considerations I should be aware of?

Absolutely! Be mindful of the number of concurrent threads you create. Too many can lead to context switching overhead. Use asyncLimit to control concurrency.
