I'm not sure I really follow you, but I'm hoping I understood what you want from the last expression. 
#!/usr/bin/perl -W
use strict;

my $hoh;
my @array = qw|abc def ghi jkl|;

my $eval_string = 
    '$hoh->{' . (join '}{', @array) . '} = q|hello world|'; 
eval "$eval_string";

print $hoh->{abc}{def}{ghi}{jkl};

__END__

___output___

hello world

The key is to use eval in string form. That way you can construct perl code using perl and execute it to affect the current program.

perl -e '$,=$",$_=(split/\W/,$^X)[y[eval]]]+--$_],print+just,another,split,hack'er
