Treating null nullable Booleans as false leads to a number of oddities. Suppose we did, and suppose x is a nullable bool that is equal to null: if (x) Foo(); if (!x) Bar(); Neither Foo nor Bar is executed because "not null" is of course also null. (The answer to "what is...
auto data = s->Data(); // legal! returns pointer to L"" auto length = s->Length(); // legal! returns 0. auto equal = s->Equals(L"nope"); // legal! returns false. That’s right: I dereferenced a null pointerand it felt good. ...
