No it never does, since the code @{$res}->{objects} tries to dereference a hash-ref not an array.

But interestingly this magically (?) works:

  DB<112> @a="a".."d"
 => ("a", "b", "c", "d")

  DB<113> @a->[2]
 => "c"

aaaah! =)

  DB<114> use warnings; @a->[2]
Using an array as a reference is deprecated ...
