    i always use strict but got not no complaints as perl took it as a hash,
    not a reference, but i remembered it would somehow work without arrows, like this
    my $crd = ${$ref}{$key}{NAME};
      $ref{$key}{NAME} and ${$ref}{$key}{NAME} are two completely different things. But you can say that the latter is another form of arrow notation (the first arrow, because it's a dereference operator), so they are both a hash reference.
      my $env = \%ENV; print $env->{SHELL}; print ${$env}{SHELL}; print $env{SHELL}; # barks under strict, undefined otherwise # output: /bin/bash /bin/bash
