"a" for both of these. The *@ area behaves just like Perl 5's calling
conventions. I could argue for never auto flattening arrays, but then
there'd really be no difference between @ and $.

Hmm, *(@array, "z")... what does that mean? Whatever it means, you're
correct in both of these. In the latter, the @array is in a
flattening context, so it gets, well, flattened.
