Temporary Values

When writing Actions, you can reduce the amount of repeated processing within aggregate values or loops by storing computed values as temporary values.

A loop could be Existence, For all or chaining predicates, as well as While loops or Loop over objects operations.

If a calculation requires a value that will be the same across all objects that it will use, it would be better to add that as a temporary value in an action so that a separate rule isn't needed.

If each iteration of the loop is performing some non-trivial work on the current object such as buffering, then it is quicker to perform the buffering once, assign the result to a temporary value and then use the temporary value within the loop.
