The usability of

@l=%h2=reverse %h1;

may be debatable ...

But %h2 identical to %h3 in

%h3=%h2=reverse %h1;

is IMHO normal expected behavior.

The problem is related to collisions, no collisions no problems.

lanx@nc10-ubuntu:~$ perl -MData::Dumper -e ' @h1=(1 => 3, 2 => 5, 3 =>
+ 10); %h3=%h2=@h1; print Dumper \%h2,\%h3'
$VAR1 = {
          '1' => 3,
          '3' => 10,
          '2' => 5
        };
$VAR2 = {
          '1' => 3,
          '3' => 10,
          '2' => 5
        };
