Hi, just giving an example using printf: 
use strict;
use warnings;

my @accounts = [ 
    [ current => 1000 ],
    [ savings => 2000 ],
    [ other   => 500  ],
];

foreach my $sub_ref (@accounts) {
    printf "%-10s | %10d\n", $_->[0], $_->[1] for @$sub_ref;
}

[download]
Output: 
current    |       1000
savings    |       2000
other      |        500

Update: Seeing hazylife's EDIT in the code section, it came to my mind that my above code could also be simplified to: 
foreach my $sub_ref (@accounts) {
    printf "%-10s | %10d\n", @$_ for @$sub_ref;
}

Please also note that my code might look slightly more complex (nested loops) because it is working on the OP's original AoA structure, whereas other solutions presented so far were just working on simple arrays.
