Re: Calling a method from class / subclass?

One addition: $__PACKAGE__::mylog=Log::Log4perl->get_logger();

In this line of code; Log::Log4perl is a module of CPAN that generates the log files during runtime
Now as _PACKAGE_ contains the current package name then what mylog ($PACKAGE::mylog) is for. Is this for calling a variable named mylog from class in _PACKAGE_? Again, why Log::Log4perl is assigned to _PACKAGE_::mylog?? What does this mean?
