Re: Shared hash within shared hash of hash???

[zwon]

threads::shared keeps all shared variables in a separate interpreter. If you declared hash like:

my %hash : shared = ();

then hash and all its values will be stored in this dedicated interpreter. In case of:

$hash{foo} = {};

you creating anonymous hash in the current interpreter and saving reference to it in the shared interpreter which is not allowed, that's why you should create a shared copy:

$hash{foo} = shared_clone({});

Another possibility:

my %tmp : shared = ();
$hash{foo} = \%tmp;
