declaration

code is assigned via :=

square := it*it

fibonacci number := if number<2 : 1 else fibonacci(number - 1) + fibonacci it - 2

To adhere to POLA, functions can also be declared via keyword: func: ['ƒ', function, fun, fn, def, defn, define /!?!/, to… ]

func fibonacci:
     it < 2 ? 1 : fib(it-1) + fib it - 2
