Another option you may like, which uses the convenient way that Perl
stringifies arrays, with a space between each pair of elements.
It does mean that you need a temporary array variable though:
my @a = split "", "2329238023089823";
print "@a";
will output
2 3 2 9 2 3 8 0 2 3 0 8 9 8 2 3
which I think is just what you want.
BTW, note that using s/(.)/$1 /g will leave you with a trailing space, which
almost certainly doesn't matter.
Cheers,
Rob
