Can anyone clarify what the expression $a->val in the code sub { $a->val <=> $b->val } signifies.
It should be "set to" an item from the list returned by $self->data. It looks somewhat like a dereferenced hash element, but there aren't any curly braces (it isn't $a->{val}. Is val a function that isn't listed?
Thanks for any help.
gerald.
