ehm ... I just stumbled over a strange effect when using each on an anonymous hash.

Bug or feature?

C:\>perl
my $hr = {a=>1,b=>2};
$\="\n";
while ( my ($k,$v) = each %{ $hr } ) { print qq($k => $v) }
__END__
b => 2
a => 1

C:\>perl
$\="\n";
$x=10; 
while ( my ($k,$v) = each %{ {a=>1,b=>2} } ) { print qq($k => $v); die
+ "abort" unless $x-- }
__END__
b => 2
b => 2
a => 1
b => 2
a => 1
a => 1
b => 2
b => 2
a => 1
a => 1
a => 1
abort at - line 2.

C:\>perl -E"say $]"
