Problem: I have a hash %a that is arranged like this: $a{$b}{$c}{$d} = value

I want to call a function, passing in a reference to a part of the array

$w = "xyz";
&myfunc($a_ref->$w);

[download]
I thought this would work, but I get the error
Can't call method "xyz" on unblessed reference

# My workaround
my %a = %$a_ref;       
my %b = %{$a{$w}};
my $b_ref = \%b;    
&myfunc($b_ref);

The workaround does exactly what I want, but it's ugly and eats up memory and CPU cycles. Is there a better way?

Thanks
