Functional loop

[raviqqe]

Problem

TBD

Solution

• Add a function loop expression.

Example

Sum

for n = 42 {
  if n == 0 {
    0
  } else {
    n + recur(n - 1)
  }
}

List mapping

for xs = [number 1, 2, 3] {
  if [x, ...xs] = xs {
    [number f(x()), ...recur(xs)]
  } else {
    [number]
  }
}

List reduction

for xs = [number 1, 2, 3] {
  if [x, ...xs] = xs {
    x() + recur(xs)
  } else {
    0
  }
}
