safer version of UNIVERSAL::can
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 one should
not do it. Unfortunately, not everyone heeds this warning and their bad code
can break good code.
.
This module 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.
