"This is _horrible_. If I provide a blessed array your code breaks."

Thanks, I can't believe I didn't see that. I should have used
UNIVERSAL::isa( )
It's strange that I posted something to CPLM a little while back that talked about this. Merlyn chimed in too, explaining why using this technique rather than using CORE::ref( ) was the scalable, portable, correct WTDI. (tmtowtdi).
