Okay, I see now, but it's indeed a weak dictionary so I guess we cannot use this for reliably deprecating the World binding.


Best,

Christoph

There's likely others but this one I remembered ;)

Are there any pointers to the concept of Undeclared? It seems to be a weak dictionary, so this does not look like a durable compatibility solution to me.

Best,
Christoph

Karl,

Thank you very much!

Indeed, great sleuthing!

Clearly we have introduced a bug in trunk since the 5.3 release, so
we'll need to fix that.

But to my original question - I was able to start with a fresh 5.3
image, and I can load CarAndPen.014.pr<http://CarAndPen.014.pr> without problems.

Then I removed the #World binding, and tried loading CarAndPen.014.pr<http://CarAndPen.014.pr>
to find out what the errors would look like.

Big surprise - There was no error. The project still loads and runs
as before. That is not what I expected, so I'm glad we checked.

Wouldn't the binding still live in Undeclared?
