c-api and CXCursor_CXXForRangeStmt

It seems that the C-api doesn't give us much info about the container
that's being iterated. The only cursor I get for the cursor at
location 2:14 is a CXCursor_DeclStmt that doesn't reference anything.

1: std::vector<int> ints;
2: for (int i : ints) {}

Is this by design? It makes it hard for our code navigation tool to
handle these loops.
