[perl #119359] perlvar/Errno contradict each other about %!

That could surely be expressed more clearly, but they don't actually
contradict one another.  %! is provided by Errno, but you don't need to
C<use> it: Errno is automatically loaded when %! is seen:

eirik@greencat[01:02:27]~$ perl -E 'say for keys %INC'
feature.pm
eirik@greencat[01:02:57]~$ perl -E 'say for keys %INC; say tied(%!)'
Exporter.pm
strict.pm
Errno.pm
feature.pm
Errno=HASH(0x987ff8)
eirik@greencat[01:02:58]~$ perl -E 'say for keys %INC; say tied(%!) if 0'
Exporter.pm
strict.pm
Errno.pm
feature.pm
eirik@greencat[01:03:00]~$
