Reading S16, I was struck by the lack of abstraction over the
underlying Unix API for chown and chmod. Nothing wrong with having the
existing functions lying about in a module that people can use Unix
for; but I do feel that the variants in the global namespace should be
more user-friendly.

I don't think that's such a good idea in this case. If a file is
chown'able is not a property of the chown function, but of the file.

Hi all, what's wrong with this code:

{
my $a = $x * 2;
my $b = $y * 2;
return($a, $b);

The restriction of chown to the superuser is a property of the OS, not the
files. The example from the pod is:
use POSIX qw(sysconf _PC_CHOWN_RESTRICTED);
my $can_chown_giveaway = not sysconf(_PC_CHOWN_RESTRICTED);
Thinking about it, perhaps that means that it's a method on $*OS.
