The problem with this approach is if you now run `echo Buffet("Noodles")` (with only one variable), Vim complains that it has an undefined variable `a:2`. How can you make it flexible enough to display exactly what the user gives?

Luckily, Vim has a special variable `a:0` to display the *length* of the argument passed into `...`.
