## Status

ACCEPTED

## Consequences

* If we would have used `Closure`, we must instead use `Action<T>`, `Spec<T>`, `Callable<T>`, or `Transformer<OUT, IN>`.
* We need to ensure all APIs that are exposed in the Groovy DSL go through runtime decoration.
Runtime decoration mixes in methods that use Groovy Closures to maintain consistent behavior in Groovy DSL.
