Re: recursively reduce an array

[Limbic~Region]

Anonymous Monk,
Hashes aren't sorted - even with Tie::Hash::Sorted which appears to be sorted, there are things going on under the covers to make it look like it is sorted.

It sounds like what you have is this:

my @sorted_keys = sort keys %hash;

while (@sorted_keys) {
    my @ten = splice(@sorted_keys, 0, 10);
    # Do something with @ten
}

If that isn't what you mean, you will need to try and provide more context or hope one of the other monks has guessed better than myself.
