Fibonacci
fib.hd
With a function
With a lambda
func calculate(n)
    if((n is 0) or (n is 1))
        put n
    end
    
    put fib(n-1) + fib(n-2)
end
var calculate = { x => (x == 0) or (x == 1) ? x : calculate(x-1) + calculate(x-2) }
main.hd
with fib from fib.hd
with console from std:io
with Int fixed from std:int
​
fib->calculate:parse(value=console->in(),raise=false,defaultValue=0)
