k, I don't know if I should be embarrassed about this or not... but can
someone point out a cheaper way of creating an array of token chains?
(one that doesn't compromise code maintenance. :)
The objective is to ensure the length of the chains can vary over a
range... which this datastructure seems to do. I'm looking for a
perspective not biased like mine might be, or someone's experience...
or just an opportunity to learn something. :)
(uh, I'm also aware i'll have to make some minor changes to allow
arrays anywhere along the chain where needed -- this is just some
test code.)
code:
============================== hohoa.pl ==============================
#! /usr/bin/perl -w
use strict;
use Data::Dumper;
my @hash_elements = ("my","very","earnest","mother","just","served","us","nine","pickles");
my $end = pop @hash_elements;
my $href;
for my $idx ( reverse 0 .. $#hash_elements )
{
my $elem = $hash_elements[$idx];
if ( ref($end) ) {
$href = { $elem => $end };
} else {
$href = { $elem => [$end] };
#push @{$href->{$elem}}, "foo";
}
$end = $href;
}
print Dumper($href);

For this could be the biggest sky
And I could have the faintest idea
