There are VERY FEW situations that require this kind of
action... but assuming you have one then the well proven
shortest approach is:
$string = "Hello World";
@string = $string =~ /./g;
OR:
$string = "Hello World";
for ($string =~ /./g) { print $_."\n"}
Split on a null length string is probably more readable,
but this simple technique works for pairs of characters...
and allows you to avoid pack() and unpack() a little
longer!
Take care,
