Hi, I haven't noticed this before, but I think this is a bug. It should behave like a regular slot and it shouldn't have a different icon I think. If a watcher is not possible because of computational load you should at least be able to append operators. When you drop it on a test tile it doesn't append comparison operators so you end up with a NonBooleanReceiver error. I don't know how to fix it, I tried to add the watcher by modifying #phraseForVariableFrom: but it didn't work quite well. Perhaps someone more experienced than me should take a look at this.
Cheers.

Hi,
In Etoy viewers, some of the slots like bearingTo don't have watchers on them. They don't act like number tiles in assignments. It is disturbing to drop them into assignments and not be able to append arith operators. Is this because of computational load?
If so, could a different icon (say yellow menu instead of a white one) be used for such slots?
