[gathering-options] Arrow symbol

[Howard Lovatt]

May I make a three of suggestions:

1. Include a null argument example
2. Include a curry example
3. We include the syntax with optional () and optional {}, i.e.:

-> 42
() -> 42
x ->   x + 1
(x) ->   {x + 1}
(x, y) -> { 
  if (x > y) 
    return x; 
  else 
    return y; 
}
x -> y -> x + y
