An example of an AI chatbot conversation about MVars in Haskell, a concurrency primitive.
What are MVars in Haskell?
MVars are mutable variables used for synchronization in concurrent Haskell programs. They can be empty or contain a value.
How do I create an MVar?
You can create an MVar using the newMVar function, which initializes it as empty or with a value.
Can you give me an example of using MVars?
Sure! Here's a simple example: you can use takeMVar to take a value from an MVar and putMVar to put a value back.
What happens if I try to take from an empty MVar?
If you try to take from an empty MVar, the thread will block until a value is available.
