Quote: what mylog ($PACKAGE::mylog) is for

To store the value you need variable name: that's $mylog. To store it in the current package, you can use $__PACKAGE__::mylog.

Quote: Again, why Log::Log4perl is assigned to _PACKAGE_::mylog?? What does this mean?

It could mean a number of things. One of them could be that author of the code wants a package global variable (variable that is global in the package defined) to be accessed from outside of the package.
