# Bug with "regionally in" or in Index?

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?

It looks like an index bug; the relation should be shows as “region to room”.

Hm. Maybe it’s deeper than that. I’m getting weird errors with

The RRR is a relation that varies.
… now RRR is the regional-containment relation.

I submitted a cosmetic bug. We’ll let wiser heads figure it out.
