Functions

sum = fn [a b] a + b

-- invoking sum...
sum: 1, 2

-- functions can also be invoked with pipes
sum: 1, 2 | print        -- print(sum(1, 2))

-- multiple expressions can be piped together
1 | id | print           -- print(id(1))

-- previous args are carried over into function calls
-- also have some sugar functions such for operations like comparisons.
1 | sum: 2 | (== 3)   -- sum(2, 1) == 3

-- function expressions with a body
fib = fn [n] {
  if n < 2
    then n
    else (fib: n - 1) + (fib: n - 2)
}

-- IIFE
(fn [] {
  number-of-balloons = 99
}): none

-- Anonymous functions
fn [x] x * x

-- we can pass those as args
call-function = fn [f arg] f: arg
call-function: (fn [x] x * x), 9      -- 81

-- There's also Pattern Matching and Guards
fact = fn [n]
  1 ? 1
  else ? n * (fact: n - 1)

-- splits up the list into x = head(list) and xs = tail(list)
sort-even-odd = fn [[x, & xs]]
  not x ? []
  odd: x ? (sort-even-odd: xs) ++ [x]
  else ? x +: (sort-even-odd: xs)

  [1 2 3 4 5 6] | sort-even-odd | assert-deep: [2 4 6 5 3 1]
