### Transformation constraints

In order for the framework to properly handle dependencies and events, transformation functions must adhere by a few properties.

Basically, Transformations must be stateless and idempotent.
* Any querying of other `Collection`s _must_ be done through `krt.Fetch`.
* Querying other data stores that may change is not permitted.
* Querying external state (e.g. making HTTP calls) is not permitted.
