in reply to Counting keys in a referenced hash

$test doesn't refer to a hash ...
it actually gets the last element from the list which is '3'.

apply the following change:

$test = { test1 => '1', test2 => '2', test3 => '3'};

[thepkd]: $aohoaoh ->{'foo'} has to be dereferenced to access its contents right?
[thepkd]: sorry. i mean $aohoaoh[0]
[GotToBTru]: $aohoaoh is an array reference tho
[thepkd]: some guy was suggesting $aohoaoh[0]->{'foo '}[0]->{}. This wouldnt work.
[GotToBTru]: you're mixing notation there I think
[GotToBTru]: $aohoaoh->[0] is a hash reference, so $aohoaoh->[0]->{ key1} would work
