The situation is thus:
I'd like to use hashed and arrayed data, being passed into a function as references, using non-de-referencing notation.
Instead of $array_ref->[0], I want to assign the data referenced by $array_ref to something like @array_by_another_name, so that I can then just say $array_by_another_name[0].
If I just assign the de-referenced data to a like variable I will get a copy... (ie my @array2 = @{$array_ref}; is not what I want).
my %foo = ('a' => 1);
my_sub(\%foo);

sub my_sub {
 my $foo_ref = shift;

 #Now I want to do something here to name %bar as pointing to %foo:
 #my %bar ????? $foo_ref;

 #such that 
 print $bar{a};
 #prints '1'

 #and if I were to
 $bar{b} = 2;
};

print $foo{b};
#prints '2'

I think I have a good grasp on wrangling references... but I'm always up for elucidation. This would indeed be like a hard reference on a unix system- it increases the reference count, but is otherwise treated like it IS what it refers to- no de-referencing needed.
