    I have ｢A.rakumod｣ which exports two multi variations of
    subroutine ｢orig｣. I would like the user to be able to do for
    example ｢use A 'mine'｣, so that they can invoke the exported subs
    with some other arbitrary name instead.

As explained in this talk by lizmat,
<https://www.youtube.com/watch?v=VoxWnNJ0gTI&t=8440s>, to speed up the
launch time of a Raku script, one can write all of its MAIN logic in a
module, make sure sub MAIN is exported, and create a script that
simply "use"s the module (the talk is more general and worth
watching). The launch time speedup will occur once the program has
been run at least once, since its modules will have been precompiled,
as opposed to the script itself.

But what if we want to have a custom USAGE() function? We can write

" or something.

function! ExecHighlighted () range

        " Grab the highlighted text: save the contents of an arbitrary
        " register, yank the highlighted text to it, copy the register
        " contents to a local variable, and restore the register
