Official Mirror:
The UNIVERSAL class provides a few default methods so that all objects can use them. Object orientation allows programmers to override these methods in subclasses to provide more specific and appropriate behavior. Some authors call methods in the UNIVERSAL class on potential invocants as functions, bypassing any possible overriding. This is wrong and you should not do it. Unfortunately, not everyone heeds this warning and their bad code can break your good code. Fortunately, this upstream_name replaces UNIVERSAL::can() with a method that checks to see if the first argument is a valid invocant (whether an object -- a blessed referent -- or the name of a class). If so, and if the invocant's class has its own can() method, it calls that as a method. Otherwise, everything works as you might expect. If someone attempts to call UNIVERSAL::can() as a function, this module will emit a lexical warning (see perllexwarn) to that effect. You can disable it with no warnings; or no warnings 'UNIVERSAL::isa';, but don't do that; fix the code instead.
