While I'm doing last-minute research for /my/ book, I've got to learn
to stop believing what I'm reading in /other/ books! 

As a case in point, my 3rd edition Camel (7/00) was probably
describing the behavior of Perl v5.6.0, and accurately representing
the behavior of glob() at that time.

However, it seems that File::Glob (which glob() calls) started
using bsd_glob() instead of the old Csh-based code some time
after the Camel's publication, which accounts for the mismatch
between the Camel's pronouncements and the reality of the current
state of Perl.

So I retract my complaint about the Camel, and re-allocate it to
the on-line docs for the Perl versions I tested (5.8.0,
5.8.5). In each, "perldoc -f glob" says csh-style behavior is
what glob gives you, which is incorrect at least in regard
to the "!" vs "^" character-class complementing character
(Perl uses the non-C-sh ! now, rather than the Csh's ^).

We can't blame a book for getting out of date, but we can
certainly hope that the on-line documentation shipped with Perl
itself will be in sync with the software.

I'll file a bug report.
