I think what you're trying to do is something like this:
my %test = ('a' => {'b' => 'c'});
while ( my($name1, $value1) = each %test )
{
print "$name1:\n";
if(ref $value1 eq 'HASH') {
while ( my($name2, $value2) = each %$value1 )
{
print " $name2: $value2\n";
}
}
else {
print "$value1\n";
}
}
which prints:
a:
b: c
The test using ref might be a bit superfluous here, but it opens the door to indeed making the implementation using a recursive sub, and for using uneven leveled hashes. This way, you can nest to an indefinite level.
