Hi Monks,

I am having the great joy of figuring out someone else code. And I haven't seen this before ... 

$tests->{$stype} ||= {};
my %tests = %{$tests->{$stype}};

... what the heck would that code be trying to do?

The $test is a big ugly global hash ref at the top of the code that is about 100 lines long so I will only post a small version that might have typos in it here: 

my $tests = {
    all => {
        cost      => \&cost_checker
    },
    YEAM => {
        lipmons => sub { check_lipmons(@_, 'SD'  => 3,
                                           'ron' => 2,
                                           'SP' => 3); },
        dd          => \&check_dd,
        stype     => sub { check_stypes(@_, "EM"); },
        heat_monr => sub { check_heatmonr(@_, 1); },
        heat_pgm     => sub { check_hpgm(@_, 'Solar'); },
    },
    ...

Thanks
