In this code $var is declared in program. What package does it belong to ? What is main package ? If I declare $var in a program, does it automatically belong to main package ? If I declare variable $anything , which does not exist in main package. Now , if I use strict, is it required to use main before the $anything ($main::anything) ? How does $anything become a part of main package ? Or does main mean main body (and not subroutines) of program that we are dealing with ? So does it mean that everything from "#!/usr/bin/perl" to the "print $var; " excluding subroutines is main ?
