# Example

[examples/fibonacci.rcl](examples/fibonacci.rcl)

```ruby

#include ../selfhost/lib/std.rcl

def fib(n)

  case

  when (n < 0)

    _panic();

  when (n < 3)

    return n;

  else

    return fib(__sub(n, 2)) + fib(__sub(n, 1));

  end

end

def main()

  var n = 0;

  while (n < 21)

    print_i(n);

    putchar(C_SPC());

    print_i(fib(n));

    putchar(C_LF());

    n = n + 1;

  end

end

```
