UNIVERSAL it's base class for all classes in perl, UNIVERSAL::isa is
function/method which tell you if object is blessed in package or
inherits from package. It's basic, fundamental concept when you
programing in Object Oriented Perl. I don't think that I could explain
what isa really does in short description without explaining classes and
objects in Perl.
