in reply to Module Loading via Exporter doubt.

Inheriting from Exporter means that your module gains a function which is defined in the Exporter package, the "import" function. This means that anyone "using" your package will call Exporters import, to import your exported functions.

You don't need to "use" Exporter, since you do not need any functions from Exporter in your modules namespace.

No, no symbols in your package are automatically exported, you need to tell it exactly which ones you want to export, using the @EXPORT_OK variable.

In short, when someone "uses" your package, which is in turn inheriting from Exporter, the import function is called, which looks at your @EXPORT_OK variable, to decide which symbols to import into the calling codes namespace.

    To be complete, I'd like to add: Exporter looks not only at @EXPORT_OK, but also @EXPORT and %EXPORT_TAGS. My personal preference is to use @EXPORT_OK rather than @EXPORT because I feel is is more polite. %EXPORT_TAGS can also be quite useful when properly used.
