} In other words, if the argument to shift is a parameter that isn't an
} array, it's used to give a mathematical value with which to shift the
} positional parameters. That seems confusing.
I can't disagree that it's confusing, but the idea is that you can give
any math expression there, e.g. "shift 7-foo" would shift by 4. This
is in the same category as passing math expressions to "return".
It's always been like that ...
