DataKernel has an extremely lightweight DI with ground-breaking design principles. It supports nested scopes, singletons, object factories, modules and plugins which allow to transform graph of dependencies at startup time without any reflection.

The newest version!

/**
 * If module provides at least one binding marked as exported then all non-exported bindings
 * will be visible only from bindings inside of the module.
 * Injector would only be able to retrieve the exported bindings.
 * 
 * If no bindings are exported then all of them are - this is made for backwards-compatibility and simplicity.
 * Module that has bindings but exports none of them is useless - binding generators only work with exported (or 'public') bindings.
