An example of an AI chatbot conversation about Haskell error handling best practices.
What are the best practices for error handling in Haskell?
In Haskell, best practices for error handling include using types like 'Maybe' and 'Either' to represent computations that can fail.
Can you explain how 'Maybe' works in Haskell?
Sure! 'Maybe' is a type that can either be 'Just a' (indicating a successful result) or 'Nothing' (indicating failure).
What about using 'Either'? How is it different from 'Maybe'?
'Either' is similar to 'Maybe', but it allows you to store an error message or value in the 'Left' side, while 'Right' is for success.
Are there any libraries that can help with error handling in Haskell?
Yes, libraries like 'transformers' and 'mtl' provide monad transformers that can help manage error handling more effectively.
