Summary0000437: Inform confused between defining a grammar token and defining synonyms for a class of object
DescriptionThis is the report produced by Inform 7 (build 6F95) on its most recent run through:

Problem. You wrote 'Understand "box" as a cube' : but grammar tokens must have the same outcome whatever the way they are reached, so writing a line like 'Understand "within" or "next to [something]" as "[my token]" must be wrong: one way it produces a thing, the other way it doesn't.

See the manual: 16.13 > New tokens


The error message above was produced by the source code below. If I remove either "understand" statement, it works just fine. I believe that this source code should be compiling correctly but may be confused. Either way, the error message is faulty.
Minimal Source Text To Reproduce
Room 1 is a room.

Color is a kind of value. The color are red and blue.

A cube is a kind of thing. A cube has a color. The color of a cube is usually red. Understand "[color]" 
as a cube. Understand "box" as a cube.
Additional InformationZarf confirmed on that there is a bug involved here. ( [^])
TagsNo tags attached.
Effect(serious) Compiler rejects valid code

Fixed, though note that as a result,

Understand "[color]" as a cube.

makes any color refer to any cube. But this is logically right.
