This is a bug report for perl from camel@abigail.nl,
generated with the help of perlbug 1.34 running under perl v5.8.1.


-----------------------------------------------------------------
[Please enter your report here]

If I run the following program in 5.8.0, 5.8.1 or the current 5.8.2-to-be
(how do we call it? bleadmaint?):

    #!/usr/bin/perl
 
    use strict;
    use warnings;
 
    sub bug (\[%@]) {
        my $arg = shift;
 
        print ref $arg, "\n";
    }
 
    my $array = [0 .. 1];
    my $hash  = {foo => 'bar'};
 
    bug %$array;
    bug @$hash;
    __END__

I get:

    ARRAY
    Not an ARRAY reference at /tmp/bug line 16.

which is not what I would expect. I would expect:

    Not a HASH reference at /tmp/bug line 15.

and that's what bleadperl gives me.
