I prefer the use of Optional. I could live, begrudgingly, with OptionalInt, but i don't think there is a strong technical requirement for it. The argument against OptionalInt vs Optional is basically "OMG, N more classes." If we did Doug's "Numeric" trick, we could get away with one new OptionalNumeric class.

There is a big difference between OptionalInt to Optional, OptionalInt can be retrofitted to a value type at least with the current plan where Optional requires full generification to be seen as a value type.
