Proposal: Return expression

[ronnygunawan]

A return expression works similar to throw expression. It invokes a return statement when evaluated.

void Hello(Person? p) {
    string name = p?.Name ?? return;
    Console.WriteLine($"Hello {name}");
}

int? GetAgeOrDefault(List<Person> people, string name) {
    Person person = people.FirstOrDefault(p => p.Name == name) ?? return null;
    Debug.Assert(person.Age > 0);
    return person.Age;
}
