BMaximus has asked for the wisdom of the Perl Monks concerning the following question:
Could someone give an example on the proper use of the Safe module. In the Panther book eval allows the use of a variable like so.
My thanks for your enlightenment,
BMaximus
The printout should be 9. Now when I use Safe on a module it doesn't turn out quite the same way.my $c; my $ev = '$c = 4 + 5'; eval($ev); print $c;
When $c is printed out its nothing. Whats going on in Safe? Whats an example of its proper use?my $c; my $cpt = new Safe; $cpt->share('$c'); my $ev = '$c = 4 + 5'; $cpt->reval($ev); print $c;
My thanks for your enlightenment,
BMaximus
