Ionflux and WClientWin

[?????????]

Hello.   I am using ion2 stable with mod_ionflux and I have a question about it:   How can I access current WClientWin from ionflux to use toggle_fullscreen or kill? The only way to do it, which I find:   ionflux -e 'return WClientWin.toggle_fullscreen(lookup_clientwin(WRegion.name(WRegion.active_sub(WIonWS.current(find_screen_id(0))))))'   It doesn't look as it is supposed to be and works for WIonWS only.   I am looking forward for you answer.   Thank you for very good window manager.
