Exactly backwards.  Test::MockObject and Test::MockObject::Extends both 
overload isa() and can.  Stupid, buggy, short-sighted, and wrong code that 
calls UNIVERSAL::isa() and UNIVERSAL::can() as functions breaks it.

Calling sv_derived_from() in XS code and expecting it to work on Perl objects 
is likewise wrong-headed.
