+The L<Alien::Base> system needs to store some data to be used in other phases of the build and eventual use. This is done via the mechanism provided by L<Module::Build::ConfigData>. During the build-phase this information is mutable and is available through the C<Module::Build::config_data> method. As the build-phase ends the data is serialized and stored as C<Alien::MyModule::ConfigData> (assuming you are authoring C<Alien::MyModule>). Then during the use-phase, the C<Alien::MyModule::ConfigData::config> method (via the C<Alien::MyModule::config> wrapper) is used to query the information. This data is not strictly immutable, but it changing it involves file permissions and is best left alone.
