$ perl -wE '$data = [{"data" => "foo"}]; say @$data[0]->{"data"}'
foo

[download]
However, I would write that as 
$$data[0]{"data"}

[download]
which doesn't use an unneeded arrow, and uses the more usual dereference sigil. (I guess this case isn't caught by "Scalar value @... is better written as $...).
