Yes: scalar in list context.
> for ($arrayref) {...}; # loop body executed one or three times?
Same thing: scalar in list context. So once.
> for $arrayref {...}; # loop body executed one or three times?
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.
