The last two lines of the example read:

int j;
auto x3 = []()->auto&& { return j; }; // OK: return type is int&

However j is not captured and the lambda doesn't have a default capture.

The correct code should be:

int j;
auto x3 = [&]()->auto&& { return j; }; // OK: return type is int&
           ^

I think j should be interpreted as having namespace scope, so it needn't (and can't) be captured.

My bad., I wrongly reproduced the example with j in a local scope.
