Here's a little trick you might like:
[code]
errordomain MyError {
FAILED;

T throwerror<T> (string str) throws Error {
throw new MyError.FAILED (str);

int func ()
{
int? i = null;
int j = i ?? throwerror<int> ("hello");
return j;
}
[/code]
Looks great, but I can't get it to compile with experimental non null since the ?? operator is returning an 'int?' IMHO, as nice as this solution is, it seems a bit hackish for a language that claims to support non-null types. Overall, Vala provides very few features that make N.N. types more attractive compared to regular types and personally I find them a pain to work with
