Summary0000698: Internal error when understanding a non-EO property as describing too broad a class of things
Description- - - -
Problem. An internal error has occurred: non-EO property. The current sentence is 'Understand the flop property as describing a thing' ; the error was detected at line 144 of "Chapter 17/Either-Or Properties.w". This should never happen, and I am now halting in abject failure.

Perhaps the error should have been

- - - -
Problem. You wrote 'Understand the flop property as describing a thing' : but that property is not allowed for the thing or kind in question, just as (ordinarily) 'understand the open property as describing a device' would not be allowed because it makes no sense to call a device 'open'.
 See the manual: 16.15 > Understanding things by their properties

Minimal Source Text To Reproduce
There is a room.
Here is a thing called the shoe.
The shoe has a number called the flop.
Understand the flop property as describing a thing.

Fixed. (Though the supplied source text is actually incorrect, because the number property belongs only to the shoe, not to things in general, as would be needed to give effect to the Understand sentence.)
