The idea behind this sub is that $static gets incremented each time you
call the subroutine. If that is not what you want then yes, the if-else
is not needed. In that case you would want to say something like:
sub sub1 {
my $static if 0;
#this line is not necessary unless you need
#a default value for you static variable
$static = "DEFAULT" unless defined $static;
#do something
}
