in reply to Need of using Exporter to export package variables

Hi kbperl,

...When I declare variables as our <variable_name> in one of the module(say when i try to access them in other modules(say, i am able to do so when I don't use "use strict" and including in
And why is that? Because using say: $ModuleA::value_to_get should get the value for you, while strict is enabled and in fact, even when use Exporter; is not used in "ModuleA" this still works. However, it's NOT good practice to even export modules variables to start with.

Is the reason to use exporter module is to export only a subset of the package variables or is there some other reason for this?

If you show me, I'll remember.
if you involve me, I'll understand.
