The documentation and the code of the module are looking inconsistent. The documentation says:

the arguments have different names (and probably different meaning as well).

    It is the OO Perl. The first argument is the invocant, the second argument is the interval (but according to the documentation, might as well be an array ref). The rest of the parameters are left in @_ to be used later.

    Handling the array ref:

    if (ref $millis eq 'ARRAY') { $callback = Tk::Callback->new($millis->[1]); $millis = $millis->[0]; }

    Handling the remaining variable references:

    foreach my $vref (@_) {

    The module description stems from the 'Mastering Perl/Tk' bible. Both usage formats are described as valid. I choose the more 'simple' one.
