When I find myself being too clever (or find that I have been too clever in a previous version of code), I try to simplify it. If I don't, I find myself spending way too much time trying to understand the clever code I wrote yesterday (or last week / month / year), and wanting to go back and smack some sense into myself. 

push @{$outp}, sprintf '"%s"=>"%s"', @$_ foreach
      @{&{ sub ($) { my $_=["",[]];
        push @{$_->[1]},\@{$_->[0]} while @{$_->[0]=[each $_[0]]}; 
        $_->[1] } } (\%ahash)}, @{$v};

There is a lot packed into that code example that could probably be made more understandable, at the very least, with some whitespace. 

push @{$outp},
     sprintf '"%s"=>"%s"', @$_
         foreach @{&{
             sub ($) {
                 my $_=["",[]];
                 push @{$_->[1]}, \@{$_->[0]}
                     while @{$_->[0]=[each $_[0]]}; 
                 $_->[1]
             }
         } (\%ahash)},
     @{$v};

although, in this case, I would probably give it some more care and feeding than just whitespace. Specifically (assuming that I am understanding what you are attempting to do), I would look at using map (map { sprintf... } along with keys instead of the foreach structure that you have.

Assuming that I am understanding your intent (which I still may not have grokked), does this do what you are attempting?

push @{$outp},
    (
        map {
           sprintf '"%s"=>"%s"', $_, $ahash{$_};
        } keys $ahash,
    ),
    @{$v};
