The syntax @array->[0] is unsupported; it was never really intended to work in the first place.

The perldelta that comes with 5.6.1 explains:

Arrow operator and arrays When the left argument to the arrow operator "->" is an array, or the "scalar" operator operating on an array, the result of the operation must be considered erroneous. For example: @x->[2] scalar(@x)->[2] These expressions will get run-time errors in some future release of Perl.
I think that your tutorial is somewhat misleading, because you seem to suggest that @array->[0] is a standard idiom.
