Testcase

struct bla {
int one{0};
int two{0};
}
Vc::vector<bla> test={bla1, bla2, bla3, bla4, bla5, bla6, bla7, bla8, bla9, bla10};
Vc::int_v::IndexType indices = Vc::int_v::IndexesFromZero() + 4;
Vc::int_m mask = indices < (test.size() - 1);
// how can I apply the mask here?
auto blibla = test[indices][&bla::one];

The gather and scatter methods which allow for masks are deprecated. How can I still use masked gather and scatter?
Any help is much appreciated :)
