Hi monks,

I've noticed a weird behavior of a very simple loop with a warn statement.

#!/usr/bin/perl
use strict;
use warnings;

for my $f (qw(a b)){
        print $f;
        warn ".";
}
[download]

This code runs as expected an produces thew following output:

. at test.pl line 7.
. at test.pl line 7.
ab

However, if I don't put an argument to warn:

#!/usr/bin/perl
use strict;
use warnings;

for my $f (qw(a b)){
        print $f;
        warn ;
}
[download]

I get the following output:

Warning: something's wrong at test.pl line 7.
Warning: something's wrong at test.pl line 7.
a1
[download]

Notice the "1" instead of "b".

Any ideas about this behavior?

My perl version:

$ perl -v

This is perl, v5.8.8 built for i486-linux-gnu-thread-multi
