This in fact is not true. Funnily you can add *one* comma at the end of any
list-like construct. I have not digged into documentation to find out where
this is described (or whether it is an unnoticed "bug"). I consider this a
"good thing" however, because it eases editing when you put your items on
single rows. In this case the comma is more a "terminator" than a
"separator"
