lightweight subset of Exporter

Exporter::Lite is an alternative to Exporter, intended to provide a lightweight subset of the most commonly-used functionality. It supports import(), @EXPORT and @EXPORT_OK and not a whole lot else.

Exporter::Lite simply exports its import() function into your namespace. This might be called a "mix-in" or a "role".

When Exporter::Lite was written, if you wanted to use Exporter you had to write something like this:

 use Exporter;
 our @ISA = qw/ Exporter /;

Exporter::Lite saved you from writing that second line. But since before 2010 you've been able to write:

 use Exporter qw/ import /;

which imports the import function into your namespace from Exporter.

As a result, it is recommended to use Exporter now, as it's a core module (shipped with Perl).
