Er, these days 'for' is more like 'map', and hence returns a list.
So it's dependent on at least one iteration returning a non-() value.
In fact, if the final iteration returned False, the list would be
considered true.


The situation the thread is referring to has @invoice empty so no iterations are taking place and all this is a non-issue. :)
