in reply to Arrow Operator Oddment

My reading of perlop has me convinced that this is an unintended syntactic feature.

And that's exactly what it is. When using the arrow, Perl will see whatever is left of it as a reference. Including if you have something like @l or %h.

Note that you will get the warning
Using an array as a reference is deprecated
in Perl 5.8.0.

    Deprecated, eh? Somehow I don't get the impression that it was ever precated to begin with... :-)

      Can you explain that a bit for those less enlightened monks?

      I'm a bit baffled. I don't see what the problem is.

      ($_='jjjuuusssttt annootthheer pppeeerrrlll haaaccckkeer')=~y/a-z//s;print;

        The problem is: MeowChow created a normal Array and a normal Hash:

        @l = 0..10; %h = (a => 1, b => 2);

        But then read from them as if they were a reference to an array and a reference to a hash:

        print @l->[4]; # prints 4 print %h->{b}; # prints 2

        This would be the normal way to access the array and the hash:

        print $l[4]; # prints 4 print $h{b}; # prints 2
