Sub::Exporter is an incredibly powerful module, but with that power comes
great responsibility, er- 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 and @EXPORT_OK 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.
