Monks, I am still trying to grok array slices, though my understanding is improving thanks to all your help. Now I'm wondering if / how they can /should be used with more complex data structures.

Question 1, can this code be rewritten with an array slice to decrease the repetition in setting my ($color, $fruit)?

Question 2, is this way of dealing with HOA kosher, or am I better off using a HOH here? Would be curious to hear people that love / hate this kind of code, and why.

Thanks for helping me up the learning curve! 

use warnings;
use strict;

my ($idx_color, $idx_fruit) = (0,1);

my $hoa = { keyone => ["green","apple"],
            keytwo => ["purple","plum"]
};

my ($color, $fruit) = ( $hoa->{keytwo}->[$idx_color], $hoa->{keytwo}->
+[$idx_fruit] );

print "$color $fruit"; # prints "purple plum"
