This enabled what Iverson called tacit programming, that is, programming in functional expressions containing no variables, along with powerful tools for working with such programs.
Ovo je Iversonu omogućilo ono što je zvao "šutljivo" (tacit) programiranje; to jest, programiranje u funkcijskim izrazima bez varijabli, zajedno s moćnim alatima za rad s takvim programima.
