How about removing Null-Pointers from programming languages?

Thanks for your single line of thought.

Well, that API looks like it provides about the same functionality as my maybe, plus some fail-fast flavor stuff.

To be honest, I am not a big friend of Exceptions. In my opinion it inflates the code too much.
Having a big try/catch block around every second line of code is very unpleasant to read and doesnt really make anything easier. If at all, I think having hard-to-read code is even more dangerous then possibly mixing something up with NullPointers.

But I guess this highly depends on the application you are coding.

One way or another, Maybe<T> would have to be used everywhere to guarantee valid objects or at least checking for such.

The problem is less that Maybe<T> needs some extra code, but that there is no language feature in Java with which you can guarantee a reference to be valid.
