Doing a "use Exporter;" will not do anything different than a "require Exporter;" because the import() function in Exporter
doesn't do anything because Exporter
doesn't define @EXPORT or @EXPORT_OK.
The only difference between "use base Exporter;" and either "use Exporter;" or "require Exporter;" is that "use base" will modify @ISA for you and the others make you modify it yourself. You either have to have Exporter in your @ISA or have done something like *import = \&Exporter::import; to get the benefits of Exporter.
Nothing more, nothing less.
Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
