Anybody wanted to have an array slice which can *modify* the original ? (Something not happening with the @array{..} slice notation). Here is a solution with just a minor cosmetic annoyance: WHATSIT: Create an array of lvalue anon's stored in an array, which then return the value (as an lvalue, which means it modifies the original). 
use Data::Dump qw(dump);

my @dna = qw(A T T G C);

print dump \@dna;

my @view = ( 
             sub : lvalue { $dna[1] }, 
             sub : lvalue { $dna[2] }, 
           );

#mutate

$view[0]->() = 'x';
$view[1]->() = 'x';

print dump \@dna;

$view[0] = sub : lvalue { $dna[4] };

print dump \@dna;

# print ["A", "T", "x", "G", "x"]

Imperfect: If you want to use the view in exchange to the original array, it does not work for this reason: the 
$view[0]->()

notation (which calls the lvalue anon). One would have to find a way how this notation shall work 
$view[0]

instead.
