I thought it corresponded more closely to UNIVERSAL::isa(). Your rationale
makes sense. The code being tested was something like:
use base 'Parent::Class';
My test was:
use_ok( 'Child::Class' );
isa_ok( 'Child::Class', 'Parent::Class' );
I could just as easily check @Child::Class::ISA or use UNIVERSAL::isa().

I'm not convinced my patch allows that, but I can see where this patch doesn't
really fit. Thanks!
