in thread variable interpolation while dereferencing

Hi,

But i want to access the hash reference through a
variable as i don't know how deep it may go!

Like the following:


sub add_folder("Linux/Kernel")
{
    # i want to do the foll.
    # $bkref->{folder}{Linux}{folder}{Kernel}{folder} = {};
}

[download]

So, the RHS may go to any size
and i can't hard code it
Can u help me out?

    As hint:

    my $path = 'A/B/C';
my $hr = { 'A' => {'B'=>{'C'=>'Hello'}}};

my @path = split m</>,$path;
my $ref = $hr;
while(@path){
  $ref = $ref->{ shift @path }
}
print "$ref\n"
