           print UNIVERSAL::isa($obj, 'Foo::Bar') ? 'yes' : 'no';  #not ok

       As of Perl 5.9.3, the use of "UNIVERSAL::isa" as a function has been deprecated and the method form is
       preferred instead.  Formerly, the functional form was recommended because it gave valid results even when
       the object was "undef" or an unblessed scalar.  However, the functional form makes it impossible for
       packages to override isa(), a technique which is crucial for implementing mock objects and some facades.

       Another alternative to UNIVERSAL::isa is the "_INSTANCE" method of Param::Util, which is faster.

       See the CPAN module UNIVERSAL::isa for an incendiary discussion of this topic.

       Perl::Critic::Policy::BuiltinFunctions::ProhibitUniversalIsa - Write "eval { $foo->isa($pkg) }" instead
       of "UNIVERSAL::isa($foo, $pkg)".
