generated with the help of perlbug 1.35 running under perl v5.8.8.

Both for and foreach are supposed to be synonyms.  But there is a small
difference - you can use foreach as an attribute but not for.  So

    use Attribute::Handlers;
    sub for :ATTR {
        print "Just another Perl hacker,\n";
    }
    sub foo :for {}
    foo();

is a syntax error while

    use Attribute::Handlers;
    sub foreach :ATTR {
        print "Just another Perl hacker,\n";
    }
    sub foo :foreach {}
    foo();

prints the usual message.
