I think this poll is flawed. I am lead to believe that division by zero is, in fact, illegal
I ran this script:
print "1/0 == " . 1/0 . "\n";
And it gave me the following output:
Illegal division by zero at ./dbz.pl line 2.
Therefore I drew the conclusion that division by zero is illegal. So illegal, in fact, that the Perl compiler won't even compile the script!
