As a dedicated #Inform7 spelunker, on a recurring basis I wonder "am I the only one who's noticed this?"
The List Writer Internal rule responses have two different entries for "closed" at 'E' and 'O'.

I suppose someone *could* want to rename "closed" as used in the Printing room description details (E) and the Printing inventory details (O) activities independently...
(I assume I'm usually *not* the first person to notice...I'm just a blabbing about #Inform7 outlier)
