Description: Explore various alternatives to the Exporter module for exporting symbols in Perl, including Sub::Exporter, Exporter::Tiny, and Module::Pluggable, each with unique features and advantages.

1. Sub::Exporter

Sub::Exporter is a powerful alternative to Exporter that allows for more complex exporting of subroutines. It provides a more flexible syntax and supports the creation of aliases.

2. Exporter::Tiny

Exporter::Tiny is a lightweight and faster alternative to Exporter. It has a minimalistic design and is perfect for small modules where performance is critical.

3. Module::Pluggable

Module::Pluggable is another alternative that allows for dynamic exporting of modules based on the context. It is useful for applications that require plugins or extensibility.

Example: Using Sub::Exporter

use Sub::Exporter -setup => { exports => ['hello', 'goodbye'], groups => { all => ['hello', 'goodbye'] }, }; sub hello { return "Hello, World!"; } sub goodbye { return "Goodbye, World!"; }
