Store the contents of the generator in memory (an array).
Or make a second instance of the generator.
Or make a second instance of the generator.
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
