Ah! Admittedly, I though it's the return type .. So this works
now:

immutable int b = () {
	if(1 == 1) {
		return 123;
	} else {
		return 456;
	}
}();

What I was actually looking for was how to get this to work:

immutable int b = if(1 == 1) { return 123; } else { return 456; };

But I'm happy enough with the solution through a delegate.
