So, calling sqrt with a real 0, should not come back with a complex

Again, I think this should depend on context. In Perl5, simply
use'ing Math::Complex changes the behavior of sqrt such that
sqrt(-1) returns i.
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.

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.
