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.
That's just putting the responsibility of array bounds checking on the caller.Would you want (result, ok) returned every time you indexed an array? I sure wouldn't. An associative array isn't conceptually any different.
