In your sub, just do:
my %localhash = %$publichash

A public hash sounds like a really bad idea. Why not use a
lexically scoped hash and specifically pass it into the sub?
: Example with success but maybe is possible to write it better:
:
: our $hash;

How to Perl compel to create copy of hash?
I have public hash and in sub{} I want to create local copy without
reference to original.
Example with not acceptable result:
our $hash;
$hash->{first} = 1;
$hash->{second} = 2;
&mysub;
print $hash->{second};
sub mysub {
my $new_hash = $hash; # m
