SPUG: Doc. bug on glob() in 3rd ed. Camel

[Tim Maher]

The 3rd ed. Camel, p. 727 on "glob" says [^abc] complements the
list (as in C-shell), but it is really ! that does that, as in
Bourne/Korn/Bash shells. And this documentation bug is not listed at
O'Reilly's errata page for this book.

There's a demonstration below; any comments/insights/disproofs?

-Tim

$ ls 
!.!  ^.^  a.a  b.b  o.o

$ perl -wle '$,="\n"; print <*.*>'
!.!
^.^
a.a
b.b
o.o

# 3rd ed. Camel p.727 says circumflex is negater -- NOT!

$ perl -wle '$,="\n"; print <*.[^oa]>'
^.^
a.a
o.o

# It's really "!" that's the negater:

$ perl -wle '$,="\n"; print <*.[!oa]>'
!.!
^.^
b.b

Tested on Suse Linux 8.1 with Perl 5.8.0, and SunOs 9.0, with Perl 5.8.5,
issuing Perl commands from both C-shell and Bash shell.  All results same
as shown above.  I rest my case! 8-}
