Yes: scalar in list context.

Same thing: scalar in list context. So once.

Same thing: scalar in list context. So once.

Scalars only automatically dereference in *specific* contexts. An
arrayref not used in Array context is still an arrayref, a hashref not
used in Hash context is still a hashref.

Pay attention to list context not being Array context. It does not
dereference anything.
