 A key concept here is that age is a derived fact, supported by two other facts: `birth-year` and `current-year`. If either of those supporting facts are removed from Eve, then `age` can no longer be computed. For intuition, think about modeling this calculation in a spreadsheet using three cells.
 
-One last thing to note about control flow is that we have no concept of a loop in Eve. Recursion is one way to recover looping, but set semantics and aggregates often obviate the need for recursion. In Eve, every value is actually a set. With operators defined over sets (think `map()`) and aggregation (think `reduce()`) we can actually do away with most cases where we would be tempted to use a loop.
