Importer acts as a layer between Exporter and modules which consume exports. It
is feature-compatible with Exporter, plus some much needed extras. You can use
this to import symbols from any exporter that follows Exporters specification.
The exporter modules themselves do not need to use or inherit from the Exporter
module, they just need to set @EXPORT and/or other variables.
