I was looking for some minimal code to list out a hash -- stuff that could be 'in-lined', much like (join ", " @array)
can be thrown into a print statement to list out arrays.

My "simple"(sic?) test prog right now looks like: 

#!/usr/bin/perl -w
use strict;
use 5.14.0;

my %ahash=(one=>1, two=>2, three=>3);

my $outp=[];

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


printf "{%s}\n", join ", ", @{$outp};

What would like to do is find a way to embed the push statement into the printf -- making it similar to how arrays
are printable (am I missing an easier way mabye something using 'map'? Hmmm....

Anyway, nothing earth shaking is relying on this...just a some code quirkiness I was trying to deal with...

Why are array so much easier to print out than hashes...geez...
