in reply to Copying multi-level hash

Oh, and also, now if I wanted to place the %copy hash back in the big one (just theoretically), how would I do that?

1. %hash{'key1'}{1} = %{$copy};
2. %hash{'key1'}{1} = %copy;
3. $hash{'key1'}{1} = %copy;
4. %{$hash{'key1'}{1}} = %copy;
5. %{$hash{'key1'}{1}} = %{$copy};

Though I somehow think none of those look right...

    Remember above all : a reference is a scalar value, so reference it as you would a string (e.g.) -- as long as you remember it's pointing to something, instead of containing the value you want. Since you want to set it to a hashref:

    So: 

    $hash{key1}{1} = \%copy;

    should do ya.
