explain what is going on with the arrow in this context, when nothing is being dereferencedAs already explained above, you are in fact dereferencing $_ which in the context of your map is a reference to a hash.
the arrow operator, which I though was just for class methods and deferencingHere's a summary to avoid total confusion: There are 3 cases where the array dereferences:
- $arrayref->[0]; Then there are two cases for method calls:
- $object->method; # passes $object as first argument hth
