Sub::Exporter is an incredibly powerful module, but with that
power comes great responsibility, as well as some runtime
penalties. This module is a Sub::Exporter wrapper that will
let your users just use Exporter if all they are doing is
picking exports, but use Sub::Exporter if your users try to
use Sub::Exporter's more advanced features features,
like renaming exports, if they try to use them.
Note that this module will export @EXPORT, @EXPORT_OK and
%EXPORT_TAGS package variables for Exporter to work.
Additionally, if your package uses advanced Sub::Exporter
features like currying, this module will only ever use
Sub::Exporter, so you might as well use it directly.
