Instead of a 

std := load('../vendor/std') log := std.log reduce := std.reduce each := std.each map := std.map 

numbers := [0, 1, 2, 3, 4, 5, 6] 

We can loop over a list with 
logger := num => log(num) each(numbers, logger) 
Let's create a new list with the squares of these numbers with 
squares := map(numbers, num => num * num) log(squares) 
We can get the sum of these squares by using 
sum := reduce(squares, (acc, num) => acc + num, 0) log(sum) 
$ ink loops.ink 0 1 2 3 4 5 6 {3: 9, 4: 16, 5: 25, 6: 36, 0: 0, 1: 1, 2: 4} 91
