I was a bit confused. If there is a dependency relation between y and
the inputs to an app (whether though a mapper or directly) than it has
to be satisfied for the app to run. However, when it comes to mappers,
swift allows some hidden dependencies to be expressed. For example when
some app produces "a.txt" and somewhere you say f <"a.txt">. Swift won't
enforce that.
