Perl has an auto-increment function, and it's smart enough to recognise a string and increment within case.... but sometimes it's just too smart: 
@foo = ("1zz", "zzz", "zz1", "z1z", "zz9");

foreach my $foo (@foo) {
  print "$foo autoincraments to ";
  $foo++;
  print "$foo\n";
}

gives 
1zz autoincraments to 2
zzz autoincraments to aaaa
zz1 autoincraments to zz2
z1z autoincraments to 1
zz9 autoincraments to aaa0

Now, the first is easy, and the second is cool.... but the rest? Bizzare!
