Well, the simplistic answer would be:
my %newHash = %{$h};
if $h = { a => 1, b => 2 }, then that's fine, but with subelements like
in a hash of hashes or arrays, you only copy the top level, which
*aliases* everything below that (*not* copying, just pointing back to
the subelements of the original).
