Given you have the anon hash stored in a scalar somewhere
(otherwise it's gone for good) use "keys %$referent" rather
than "keys %hash". If your referent is buried inside of a
data structure then sourround it with curlies ("{}") to
manage the order of precidence:
print keys %$hashreferent;
print keys %{ $hashreferent };
print keys %{ $hashlist[$offset] };

keys %{ $crew[0] }
