hence you need to switch to while and add an iterator method ->each to your API ° 
while (my ($widget) = $api->each( $item->{sets}{widgets})) { ... }

That would now be the ideal for me, but don't you need to instantiate the iterator before calling it? Like: 
    my $iter = $api->each( $item->{sets}{widgets} );
    while (my ($widget) = $iter->()) { ... }

I wonder if you can combine the intializer with the iterator in a single call and have it rebless itself on the first call. Algorithm::Combinatorics does something similar.
