UNIVERSAL::isa -------------- Version 1.03 - Mon Jun 22 20:34:08 UTC 2009 Attempt to recover from people calling UNIVERSAL::isa as a function # from the shell echo 'export PERL5OPT=-MUNIVERSAL::isa' >> /etc/profile # within your program use UNIVERSAL::isa; # verbose reporting use UNIVERSAL::isa 'verbose'; INSTALLATION $ perl Build.PL $ perl ./Build $ perl ./Build test $ sudo perl ./Build install APOLOGIA Whenever you use "isa" in UNIVERSAL as a function, a kitten using Test::MockObject dies. Normally, the kittens would be helpless, but if they use UNIVERSAL::isa (the module whose docs you are reading), the kittens can live long and prosper. This module replaces "UNIVERSAL::isa" with a version that makes sure that, when called as a function on objects which override "isa", "isa" will call the appropriate method on those objects In all other cases, the real "UNIVERSAL::isa" gets called directly.
