perldoc -q "How can I pass/return a {Function, FileHandle, Array,"
remember that your core signature is
my @return_list = function(@arglist);
so the only way that you can return more than one
array or hash will be by passing their refs
my ($auther, $poem, $index) = function(@arglist);
....
sub function {
....
(\%author_indexlines, \%poem_lines, \@alphabet_index, $etc)
}
then you re-ref them as
while( my ($k,$v) = each %$author )
{
....
}
