In 6.11 “A Word About In” in the manual, it describes the “regionally in” test.
if the croquet box is regionally in the mystery value, ...
where “the mystery value” is an object that varies. But the Standard Rules defines
The verb to be regionally in implies the reversed regional-containment relation.
The Standard Rules do NOT define that relation. How it is defined is a mystery to me. But in the Relations section of the Index’s Phrasebook, the regional-containment relation is defined as room-to-room, which seems wrong. Why isn’t it region-to-room or room-to-region? Or even object-to-something?
Is this a bug?
