The functors in the ForEach, StaticTransform, and DynamicTransform methods sometimes can use the index of the parameter that they are operating on. This can be a helpful diagnostic in compile and run-time errors. It is also helpful when linking parameters from one FunctionInterface with those of another. This new features are now replacing implementations using the Zip functionality that was removed earlier. The implementation is actually simplified a bit.
