I tried that and it seems to behave the same as 'ForceArray => 1'.
Everything seems to be forced into an array.

I'm very happy to report that I got it working by using 'ForceArray =>
1' and specifying [0] to pick the first (and what should be the only)
value from all of the new arrays. I'm now using
$parsed_response->{Label}[0]->{Image} in the foreach loop. Is that a
good solution?
