You could have this today via a nicely-named UFCS function:

	T orElse(T t, lazy T defaultVal) { return t is null ? defaultVal : t; }

	class C {}
	C defaultC;
	C makeC() { ... }

	auto c = makeC().orElse(defaultC);

You can even UFCS-chain it:

	auto c = makeC().orElse(makeCAnotherWay())
			.orElse(makeCYetAnotherWay())
			.orElse(defaultC);
