"The Dumper output i'm trying to achieve is..":
Has rightly pointed out by moritz, use Storable's freeze and thaw or dclone like so:

... use Storable qw(thaw freeze); ... my $frozen = freeze \@a; for my $i ( 1 .. 2 ) { $h{"$i"} = thaw $frozen; } ...
OR using dclone, in a single step
... use Storable qw(dclone); ... for my $i ( 1 .. 2 ) { $h{"$i"} = dclone \@a; } ...
The Dumper output will be what you are looking for.
Hope this helps

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

[shmem]: all else leads to trouble, even if the third argument depends on the existence of the second. That may become brittle.
[Discipulus]: but if have case like subname(15,undef,3 ) maybe bettere named parameters
[Lady_Aleena]: I don't want to have to do: alpha_menu($hash, undef, $type);
[Lady_Aleena]: Or what Discipulus said.
[shmem]: Lady_Aleena: geany supports ctags.
[Discipulus]: a good compromise can be my ($need, $opts_ref) = @_ a scalar and an hash reference
[Discipulus]: see you monks!
[Lady_Aleena]: shmem, let me get this sub rewritten, then I will look into how to use ctags in geany. Deal? 8)
[shmem]: Discipulus: yeah, that might eventually prepare the path for OO ;-)
[Lady_Aleena]: See you, Discipulus.
