In Perl "undef" is actually a value. To set $var to absolutely nothing: $var=();
I don't understand. Can you show an example in which the results of the  $var = (); and  $var = undef; and  undef $var; statements would differ?

Would there ever be an advantage (other than obfuscation) to writing  $var = (); instead of  undef $var;?
