Actually you should compare using a bare block (no BEGIN) which is the standard (older) way to have "state" variables.
I like 'state' but the old way is still useful if you need a pair of cooperating subs (or more):
% steph@ape (/home/stephan) %
% cat state_old.px
#!/usr/bin/perl+
{
my $var = 10;
sub next1 { ++$var; }
sub next1_odd {
if ($var % 2 == 0) {
++$var;
}
else {
++$var;
++$var;
}
}
}
$\ = qq{\n};
print next1() for 1..5;
print next1_odd();
% steph@ape(/home/stephan) %
% perl+ -w state_old.px
