Packages & Modules The Package Statement

The package statement switches the current naming context to a specified namespace (symbol table)

If the named package does not exists, a new namespace is first created

$i = 1; print "$i\n"; # Prints "1"
package foo;
$i = 2; print "$i\n"; # Prints "2"
package main;
print "$i\n"; # Prints "1"

The package stays in effect until either another package statement is invoked, or until the end of the end of the current block or file
