How do I handle errors in the Haskell async library?

In Haskell's async library, you can handle errors using the try function, which allows you to catch exceptions.

Can you show me an example of using try with async tasks?

Sure! Here's a simple example:

import Control.Concurrent.Async
import Control.Exception

main :: IO ()
main = do
    result <- try (async (error "This will fail")) :: IO (Either SomeException ())
    case result of
        Left ex  -> putStrLn $ "Caught an error: " ++ show ex
        Right _  -> putStrLn "Task completed successfully!"

What if I want to handle multiple async tasks and their errors?

You can use waitAny or waitEither to handle multiple tasks. Each will return the result of the first completed task, allowing you to check for errors individually.
