in reply to The best "true zero" is...

A lot of people don't seem to understand the poll... or I'm not getting their jokes, which is also possible.

Anyway, there is sometimes a wish for something that is considered zero when used in numeric context, but true when used in boolean context, that is something that will make the following print "42\n":

#!/usr/bin/perl use warnings; use strict; my $x='<some choice on the poll>'; print $x+42, "\n" if ($x);
