I need to know if I have Op permission on the current chan in a perl OnJoin
sub handler. I try to use the CChan::HasPerm method without success.

$chan->HasPerm($ZNC::CChan::Op) and $chan->HasPerm('@') all fails with the error TypeError in method 'CChan_HasPerm', argument 2 of type 'unsigned char' at ...

Am I doing it wrong (then, how to do it right) or is this a bug in znc ?

Example to reproduce the error :

sub OnJoin($$)
{
    my $self = shift;
    my ($nick, $chan) = @_;

    eval
    {
        $chan->HasPerm($ZNC::CChan::Op);
    };
    if ($@)
    {
        $self->PutModule("test with \$ZNC::CChan::Op => $@");
    };

    eval
    {
        $chan->HasPerm('@');
    };
    if ($@)
    {
        $self->PutModule("test with '\@' => $@");
    };

    return $ZNC::CONTINUE;
}

This example produce the following outpout:

[2018-01-19 12:01] <*AutoOp2> test with $ZNC::CChan::Op => TypeError in method 'CChan_HasPerm', argument 2 of type 'unsigned char' at /usr/local/etc/znc/modules/AutoOp2.pm line 73.
