The main difference compared to APL is that KAP is lazy-evaluated. This means that the language gives the developers very loose guarantees when (or if, and how many times) a function will actually be invoked. For example, | The main difference compared to APL is that KAP is lazy-evaluated. This means that the language gives the developers very loose guarantees when (or if, and how many times) a function will actually be invoked. For example, <source lang=apl inline>↑ f¨ ⍳10</source> will only make a single call to <source lang=apl inline>f</source> because <code>f¨ ⍳10</code> will not immediately evaluate the result but only return a delayed evaluation. Since all but the first result is then discarded, those results will never be computed. | ||
