Ok, so I've got a method that returns a hash like this:

return %{$obj->{$attr_name}};

And when I want to access this hash I can do this:

my %hash = $obj->method();

Splendid.

So why can't I be Lazy and do this?

foreach my $item (keys %{$obj->method()} {

My guess is that the hash gets flattened into list context by the return and somehow doesn't get coerced back into a hash by the keys function, whereas explicitly assigning it to a hash does coerce it. Anyone care to enlighten me?

Cheers,
Bill.
