I am going out on a limb here, but i believe you misread the author's comment. The author said there is no elsunless, not that you can't have an else block to catch a failed unless block. For example, you can't say this in Perl:

unless ($login and $pass) {
   print "need login and pass";
}
elsunless (valid($pass)) {
   print "invalid password";
}
else {
   print "logged in";
}
[download]

You would have to replace the elsunless block with:

elsif (!valid($pass)) {
[download]

Note that this example should not be used as a model for login/pass validation, by the way. ;)
