Motivation
We were relying on a side effect to capture and store state from the loader making the loader operation useless without some state container. I wanted to be able to eventually use this operation to driver loaders in Vue and other rendering systems.
Approach
Instead of storing a callback in the context, I'm now storing a channel which contains a stream of states. I'm now subscribing to the state and calling side effect in the operation.
How do I property type context here?
