In scanning thorugh the wiki, I haven't seen anything like this ... so I thought I'd ask here.
Do the light Item group objects allow aggregate operations?  Can you
set $Kitchen "off"
where $Kitchen is a group?
1a) How does one determine the members of a group?
Are the light items collected somewhere, such that one can iterate through them?  Is there an "All_Lights" object that one can use to iterate through the individual lights?
Sorry for asking what may be trivial questions.  Perl is not my mother tongue.
