- Can be metadata, XML, MXML, JSON, etc, a DSL or just normal code\n
- Requests are formulated by whatever config mechanism, responses set via an API\n
- Using the configuration-data to find dependencies of the root, then providing them recursively\n
- \n
- Reflection not that easy, finding good DSLs even harder\n
- - finding all dependencies for args\n- invoking Ctors (no splat)\n
- Make lookup more complicated\n
- Class-Factories, Values, Singletons, Multitons, generic Factories, etc.\n
- PostConstruct: Sorting\ndestroy/ PreDestroy: What to tear-down?\n

- Write Your Own!\n
- - \n- Modules can work in isolation and in bigger contexts\n
- \n
- Allows setting a provider that will get called as a last-ditch effort if no mapped provider is found for a type\n
- PRE_INSTANTIATE | PRE_INSTANTIATE: Before and after creating a new instance\nPRE_CONSTRUCT | POST_CONSTRUCT: Before and after injecting into an instance\n
