2019-03-17 14:40:57 +02:00
have been created, they are aliased together. This is a form of tacit pointer
dereferencing, though authors probably don't think of it that way. A normal
object variable is like a pointer to an object, rather than an object itself,
and so the following doesn't make sense:
< / p >
< blockquote >
< p > The top prize is an object that varies. The top prize is in the desk drawer.< / p >
< / blockquote >
2020-05-03 03:01:21 +03:00
< p class = "commentary" > Clearly something goes in the desk drawer, but it's quite ambiguous what: the
2019-03-17 14:40:57 +02:00
problem is that "top prize" describes some object, but it's not clear which.
(Inform generally disallows this even if the source text explicitly gives a
value for top prize.) But "player" is unusual because Inform authors are
encouraged always to describe the player object that way, and often don't
realise that it's a variable at all — and most of the time it never changes
its value, of course, but simply remains equal to "yourself" throughout play.
So we want to allow this sort of thing:
< / p >
< blockquote >
< p > The player is in the Cage.< / p >
< / blockquote >
2020-05-03 03:01:21 +03:00
< p class = "commentary" > even though it has exactly the same problem as the top prize. We get around
2019-03-17 14:40:57 +02:00
this by treating "player", in assertions, as if it were its own initial
value ("yourself") — in effect, we silently dereference it. This is
aliasing.

2019-03-17 14:40:57 +02:00
is that once the author has written "The player is Lord Collingwood.", it's
clear that the "yourself" object shouldn't appear anywhere. But there are
two problems with that: one, the I6 template code needs it to exist, even if
it isn't in the model world; and two, we've just aliased "player" to it.

another (the "victim"), so that inferences made about the victim are diverted
to the snatcher. Thus if the source text reads:

2020-05-03 03:01:21 +03:00
< p class = "commentary" > the second sentence goes through two transformations: first, because of
2019-03-17 14:40:57 +02:00
aliasing, Inform decides to draw an inference about "yourself", rather
than complaining that "player" is indefinite; and second, because of
bodysnatching, the Collingwood object (snatcher) takes over the inference
from the yourself object (victim). So Collingwood gets the spyglass, as
the source text clearly intended.

now deprecated, but is provided as synonymous with "carried" because it
was once an either/or property in the clumsier early stages of Inform 7,
and people still sometimes type it.
