This is a bug report for perl from abeltje@fikkie.local,
generated with the help of perlbug 1.34 running under perl v5.9.0.


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

This fails for every perl I have installed (5.4.5, 5.5.3, 5.6.1, 5.8.0, 
blead):

#! /usr/bin/perl -w
use strict;
$SIG{__WARN__} = sub { die "@_" };

my %hash = ( key1 => 'value1', key2 => 'value2' );

my( $val1, $val2 );
format =
@>>>>> @<<<<<<<<<<
$val1, $val2
.

# This is ok
foreach $val1 ( keys %hash ) {
    $val2 = $hash{ $val1 };
    write;
}

print_hash();

# This isn't
sub print_hash {
    foreach $val1 ( keys %hash ) {
        $val2 = $hash{ $val1 };
        write;
    }
}
__END__

We might as well document that in future sort() in scalar context *may*
make flying pigs in pink tutus spring forth from one's nostrils, too :-)
For 5.8.0 I'm happy just to document the current behaviour.
