You can also write your functions so they work either way.
Say you create your module and export the half() function as before, you can have your function look like this:
sub half {
my $number;
if (ref($_[0]) eq 'MyPackage') {
my $self = shift();
$number = shift();
} else {
$number = shift();
}
return $number / 2;
}
so that, if called via $m->half(), it works the first way, but if called just via half() it works the second way.
