  • To clarify, apply() cannot be used with rules or functions that store local data, including rules using load() and certain SAIL components. That is, the state of a SAIL component which stores local data can be preserved with a!applyComponents(), however in these cases, apply() will return an error. In summary, use a!applyComponents() any time you're iterating over a list of components or iterating over a rule that has a load() within it, otherwise use a!apply().
