> If it is not possible to occur, then it should not be part of the API. Ah, but what if it can occur, just never with what you pass in? Suppose a function is documented to throw some checked exception if some parameter is a negative number, but you pass in a positive literal/constant? In such a situation, the checked exception will never occur! With Rust, for example, this is easily done with an `unwrap()` (and, possibly, a comment) to assert said belief, but with checked exceptions, there's no way to force the compiler to squash the required check. |
