// imagine having a list that your code accesses heavily...
// but there's no guarantee said list is always initialized.
// currently, everywhere you access the list has to be written as:
somelist && somelist[index]
// my suggestion would shorten this to:
...Normally I'd create a proc for the sake of sanity checking, but that becomes non-viable when you have many frequently used lists. For now I've resorted to always having the lists initialized, but I figured I'd toss this suggestion out there.
