Description
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
jshould be interpreted as having namespace scope, so it needn't (and can't) be captured.t-lutz commentedon Jan 29, 2016
My bad., I wrongly reproduced the example with
jin a local scope.[-]Missing capture default in example 5.1.2.4[/-][+][expr.prim.lambda] Missing capture default in example 5.1.2.4[/+]
