Exporter with features of Sub::Exporter but only core dependencies
ExporterTiny supports many of SubExporter’s external-facing features including renaming imported functions with the -as, -prefix and -suffix options; explicit destinations with the into option; and alternative installers with the installler option. But it’s written in only about 40 as many lines of code and with zero non-core dependencies.
Its internal-facing interface is closer to Exporter.pm, with configuration done through the @EXPORT, @EXPORT_OK and EXPORT_TAGS package variables.
ExporterTiny performs most of its internal duties including resolution of tag names to sub names, resolution of sub names to coderefs, and installation of coderefs into the target package as method calls, which means they can be overridden to provide interesting behaviour.
