Go has an interesting solution, key lookup in a map return a
pair
(result, ok), if lookup succeeded then result is the
associated value,
if ok is false then result is undefined. I quite like this.
How can you like undefined? That's a terrible solution again
underlining Go's conflation of union and product types. --
