You could imagine a `slices` standard library package that has a regular
generic function called `slices.Remove` that removes one or a series of
elements. This seems like a smart addition to me, as the current de-facto
method isn't very expressive. I imagine this didn't exist before
because adding a new built-in function has a far higher cost than adding a
simple utility function to a package.
