Set hash equal to another

[CJason]

If I have a hash of a hash, is there a way to set another hash table equal to the "hash" of the original hash table?

For example,
$hash1 => {
"stuff1" => {
"substuff1" => "hello";
"substuff2" => "goodbye";
},
"stuff2" => {
"substuff1" => "hello";
"substuff2" => "goodbye";
},
};

And I want to do something like:
%hash2 = $hash1{"stuff1"};

Is that doable? If so, can someone point me the way?

Thanks in advance!

Well, other than the fact that your assignment syntax is all foobarred, yes it is possible.

my %hash1 = (
   "stuff1" => {
      "substuff1" => "hello",
      "substuff2" => "goodbye",
   },
   "stuff2" => {
      "substuff1" => "hello",
      "substuff2" => "goodbye",
   },
);

my %hash2 = %{$hash1{stuff1}};
# %hash2 equals (substuff1 => 'hello', substuff2 => 'goodbye');

if you correct the syntax of your hash you can do something like this:

$hash1 = {
   "stuff1" => {
      "substuff1" => "hello",
      "substuff2" => "goodbye",
   },
   "stuff2" => {
      "substuff1" => "hello",
      "substuff2" => "goodbye",
   },
};
%hash2 = %{$hash1->{stuff1}};

Sometimes that's just freeky.

Amusingly enough, once again I can't help but be snarky while you're actually nice about correcting his errors. How on earth do you hold back the snark? It's awe inspiring

First, I assume everyone that asks a question is , then I invision them in their underwear.

Hrm... interesting.

You imagine everyone is a drag queen in their underwear? And then you eat the poo of a ghost that then chases you?

I suppose everyone has their techniques. I'll give it a try

That kind of assumption just gets me into trouble

The options are: fast, cheap and right - pick any two. &

well, now that Miller has me seeing hairy chested drag-queens instead of gorgeous ladies in their undies, I'm probably going to start getting smarmy
