That won't always work:     Can't locate Scalar/Util.pm in @INC Which do you think is more likely? 1) That I blessed a non-array reference into the package named 'ARRAY' and I'll be upset that UNIVERSAL::isa() gets confused or 2) That I don't have Scalar::Util ?

I think Scalar::Util has become "core" and so in a few years, the probabilities will shift. For now, I much prefer UNIVERSAL::isa() because I like my code to work on relatively old versions of Perl and I don't mind that it is possible to break my code by doing extremely stupid things. q-:
