Well, it is a good idea to explicitly import these subroutines to avoid
having to hunt where these subroutines are coming from:
So you do:
use Module qw( func1 func2 func3 );
Instead of:
use Module;

perlboot, perltoot and perltooc have been deprecated and deleted from the Perl
documentation. See:
http://perldoc.perl.org/perlboot.html
You should use http://perldoc.perl.org/perlootut.html and
http://perldoc.perl.org/perlobj.html instead. For more resources see:
http://perl-begin.org/topics/object-oriented/ (a link to my site)
Thanks again.
