Summing Integers

We can write a function to sum a list of integers using a recursive function. This function uses a match block to handle the anchor case where the list is empty and the recursive case where the list is not empty. In the recursive case, we destructure the list into the head and tail and add the head to the result of the recursive call with the tail.

sum = func(n List<int>) int {
    match n {
      [] -> 0,
      [head, ...tail] -> head + self(tail)
    }
}

sum([1, 2, 3])

Minimum of a List

This function calculates the minimum of a list of integers. It uses a recursive function to iterate over the list and keep track of the current minimum.

t = true

min = func(m int, l List<int>) int {
    match l {
        [] -> m,
        [x, ...xs] -> match (x < m) {
           // true in multimatch is broken :(
           @t -> self(x, xs),
            _ -> self(m, xs)
        }
    }
}


l = [5, 6, 1, 7, 8]

min(1000, l)
