Are you writing plain reusable modules, or object-based modules. In object-based modules, you rarely need or want to use Exporter. You'll still want/need $VERSION and @ISA, but the rest of the variables can go.
If you're not using object-based modules, you still don't necessarily need Exporter, but it can be nice. If you still use it, it wouldn't hurt to delete @EXPORT entirely.
