  * `krt` can accept any object type, from any source, and handle them the same.
* Provide high level abstractions.
  * Controller authors can write simple transformation functions from `Input` -> `Output` (with dependencies); the framework handles all the state automatically.

## Key Primitives

The most important primitive provided is the `Collection` interface.
