Ok, you now know how to do this. Here’s why you shouldn’t! From Exporter#What-Not-to-Export:
Do not export variable names. Just because Exporter lets you do that, it does not mean you should.
@EXPORT_OK = qw( $svar @avar %hvar ); # DON'T!
Exporting variables is not a good idea. They can change under the hood, provoking horrible effects at-a-distance, that are too hard to track and to fix. Trust me: they are not worth it.
To provide the capability to set/get class-wide settings, it is best instead to provide accessors as subroutines or class methods instead.
Hope that helps,
