Module::Implementation abstracts out the process of choosing one of several underlying implementations for a module. This can be used to provide XS and pure Perl implementations of a module, or it could be used to load an implementation for a given OS or any other case of needing to provide multiple implementations. Module::Implementation is only useful when you know all the implementations ahead of time. If you want to load arbitrary implementations then you probably want something like a plugin system, not this module. WWW: https://metacpan.org/release/Module-Implementation
