There's a function named iterate in Prelude:

Nice. I followed up with that to understand how it's written.
Now, how might I do something like that but "forget" previous values to free up memory?
Garbage Collection does that for you. If all the references are gone, the memory can be freed. If you have a specific use in mind I can show you what that looks like.
