These new packages, like slices and maps, were a long time coming. So glad it's finally here.

I cannot even begin to tell you how many different itemInSlice functions I've written over the years.

We've had `slices` and `maps` in the `exp` tree for awhile; I think they're pretty widely used already.

tbh whenever I write one of these it makes me wonder if I can accomplish the same logic in a better way.
