What is the point of nothrow if it can only detect when Exception is thrown and not when Error is thrown?

It seems like the attribute is useless because you can't really use it as protection to write bugless, safe code since the nasty bugs will pass by just fine.

Array invalid index throws Error, and asserts throw Error. I'm not sure how much you could accomplish without such features. In fact, I'd consider these ESSENTIAL to writing safe code.

Bug-free code is a myth :)


Both are cases that the compiler __could__ warn you about potential possibility of them being thrown and thus allowing you to write code that makes sure it doesn't happen.


int a = array[400];

Could yield a warning stating a possible a out of bounds error.


int a = array.length >= 401 ? array[400] : 0;

Wouldn't because you're handling the case.

What I'm trying to say it would be nice to catch certain situations like that (of course not possible with all) because you'll end up having to handle them anyway after the error is thrown.
