   The simplest, stupidest, handiest helper function I've made in a while.

   Odd/Even CSS classes? A list of proxy IPs? Whatevs.

     @eaton Sorry, couldn’t help myself to write it as a generator function (which return iterators with a .next method):

     function * makeRotator (items) {
     let i = 0
     while (true) {
     yield items[i % items.length]
     i++
     }
     }

     but yeah, not sure it’s worth the complexity…

     @eaton How did you get assigning fields to the r function to type-check?! And why not just use local variables for index and items?

     @mb21 at least in TS 5.4, that all typechecks correctly — I *believe* the key is that the freshly created function being returned gets its own explicit typing based on what you pass in; you’re not relying on the typing of the makeRotator func, but I’d have to dig in a bit more.

     @mb21 unrelated to the generator-ness, I do like using i % length — hadn’t occurred to me to use that, and as a side effect, there’s an internal record of how many times the func’s been called!
