Only use Sub::Exporter if you need it

SubExporter is an incredibly powerful module, but with that power comes great responsibility, er- as well as some runtime penalties. This module is a SubExporter wrapper that will let your users just use Exporter if all they are doing is picking exports, but use SubExporter if your users try to use SubExporter’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 SubExporter features like currying, this module will only ever use SubExporter, so you might as well use it directly.
