As far as use warnings; is concerned ... i strongly believe there should be some (even "fake") warnings.pm module for perl 5.005 (or even older versions). I don't really mind if no warnings 'foo' turns off warnings completely in older perls, but the fact that as soon as you use warnings the code is incompatible with older perls is really annoying.

Actually ... there seems to be a rather easy way to make sure use warnings doesn't kill the script without having to add any file anywhere :

BEGIN {
    $INC{'warnings.pm'} = 'ignore'
        if ($] < 5.006 and !exists $INC{'warnings.pm'}) ;
}

Of course this makes the use warnings ... completely ignored.
