in thread Setting options in Tk::Optionmenu without the callback?

This is clearly The Way It's Supposed To Be Done™. In fact, I can now make a really compact (and fairly coherent) idiom:
sub my_optionmenu_callback { return unless ( $Tk::widget =~ /^Tk::Menu/ ); # do stuff... }
Thank you -- knowing how to identify the caller like that is likely to simplify many things.
