I recently used UNIVERSAL::isa($ref, 'UNIVERSAL') for this purpose.
It was good enough for me, but I have not considered how generic it

But it's *wrong* and you oughtn't ever use it where someone else might
see it and think that it's okay, because it's *wrong* a

If $object is a class name in this case, the !ref($object) in the code

First of all, I have Test::More 0.62 installed and Devel::Cover 0.55 under
Perl 5.8.2. I also have a simple test script:
$ cat test.pl
#!/usr/bin/perl
use warnings;
use strict;
use Test::More tests => 1;
$a = {};
isa_ok($a,'HASH');
...which works well under prove:
$ prove test.pl
