Fellow Monasterians,

It's easy enough to get the keys in a hash, but what about an array of hashes? All I really need are the keys from just one of the array elements, because the way I'm using the AoH, all the keys are the same in each element of the array.

It would look something like this:

my @AoH = ({'name' => 'Barney', 'age' => '34'},{'name' => 'Fred', 'age
+' => '36'},);

my %hash = $AoH[0];
print keys %hash;

__OUTPUT__
name, age

[download]

Of course, that barfs. Is there a way to do this? TIA
