Java8 Optional? #177

Hi,
Is there any plans to support the Optional type from java8 for return values of this opt methods you have?
So that I could for example do this

Optional<String> streetName = obj.optJSONObject("person")
     .flatMap(person -> person.optJSONObject("address"))
     .flatMap(adr -> adr.optString("streetName"));

Instead of checking for null values after every opt method?
