in thread RFC: Self Assessment Perl

$h = {%h} personally I never seen used this way and I'd stress the standard form to take reference as in \%h
They do different things; as the {%h} will get you a reference to a shallow copy of the hash, not just a reference to the original.
>perl -e "my %h = (1,2); my $g = {%h}; $g->{1}=3; print $h{1} . ' vs ' + . $g->{1};" 2 vs 3
I see you've spotted that in the update tho.
