Why does reverse in list context operate on () instead of @_ or @ARGV?

It's not unimportant that very little that expects a list distinguishes between an empty list and an unspecified list, and those that do* all default to $_.

* — Only print and say do. reverse in scalar context does too, but that's because it's required to accept a list in case it's called in list context.
