Summary0000689: Hatless 3 example leaves one character hatless
DescriptionRunning the "Hatless 3" example in Chapter 8.11 of basic documentation reveals flaw in some routine, possibly randomization, possibly another. Caveat - this user (Scooter) is new to Inform, but an old hand at QA.
Minimal Source Text To Reproduce
"Hatless 3" scenario of Chapter 8, section 11 in documentation. See Additional Info for 
steps to reproduce.
Additional Information1) Navigate to Chapter 8.11 in documentation.
2) Place "Hatless 3" scenario from documentation into Source Text pane.
3) Click "Go" button
4) In "Game" pane, type "Test Me" followed by <ENTER> key.
5) Repeat steps (3) and (4) several times.

RESULT: Sometimes all four characters wear hats. Often only 3 characters wear hats.
EXPECT: All four characters should wear hats in EVERY run.

THEORY: Error in Randomization routines, and/or Looping routines, and/or object references?

The problem, if it is a problem, is in the line "now the item is worn by a random hatless person"; there's nothing that prevents that from putting the hat on the player. Or maybe that's expected behavior. Anyway, take inventory when only three of the NPCs are wearing hats and you'll find that you're wearing one.

As noted, the player is eligible to receive a hat, so there is no bug in the Inform routines. If you think the example is unclear on this point, we could convert this report to a documentation bug.

I think it's a documentation bug -- the "Hatless" examples start "Suppose we want a game in which each scenario starts with the characters wearing hats -- randomly passed out." Which suggests that each character, or at least each NPC, will wear a hat. And the fact that there are four hats and four NPCs suggests that each NPC is intended to get a hat.

Maybe there isn't any outright falsehood in the documentation as it stands, but I think it is confusing. (I had to start doing showme for the hats before I realized that the PC was wearing one.)
