I thought every range at the lowest level has an `empty` property. So, in this case, it would be:if (PFResutl.toRange.empty) { writeln("Empty"); }
Yeah, but it seems, that PFResutl is a range of ranges, and the OP has the case, where both of the contained ranges are empty.
However, this does not correspond to empty of the governing range. So [[], []].empty is false whereas [[], []].joiner.empty is true.
