Now, but not then.  Programming Perl 2nd ed. was printed 18 months ago (and
finished some months before that :-) and covers Perl 5.003.

perldelta indicates that IO:: became the approved way of doing things in
5.004. I also have it on the good authority of the IO:: module author that
the IO modules weren't part of the distributed Perl core till 5.004.

Well, no, not really.  There is essentially nothing one can do in terms of
inter-process communication on a Mac that doesn't use AppleEvents.  There
is plenty one can do in perl without IO:: (especially in MacPerl, where you
use AppleEvents :-)

Actually, if we have to fully describe the distributed core we should have
covered all of the Toolbox modules in full detail, but that would have been
a set of books... (then again, Inside Mac is a set of books :-)

waiting for Chris to tell me I'm wrong about AppleEvents ... ;-)
