+This library implements a fraction of a very broad and complex usecase. It's mostly useful for applications that 
+define traits for components, and want to be able to abstract over the storage for those traits. If it doesn't offer 
+some functionality you need, check out the [`impl-tools`](https://github.com/kas-gui/impl-tools/) project.
