My specific use case was working with 'infinite lists', so the first options is ruled out. The second option could be a solution, but the specific case was reusing a variable `const nums = iu.iterate(x => x+1, 1)`, and quite extensively. (It's just a helper function to make a list of all natural numbers) It would be so much nicer if I could just reuse this variable throughout my code
