Hi,
In Etoy viewers, some of the slots like bearingTo don't have watchers on them.
Is this because of computational load?
I don't think so, but maybe Scott can enlighten us on the design reasoning? I think it made sense that only properties of the object itself have read-outs, not relationships to its environment.
I don't see why a function shouldn't have a readout. It returns a value, and IMHO all useful values should have readouts. This includes bearingTo, distanceTo, isOverColor, colorSees, overlaps, overlapsAny, and so on. I know some of them can't have readouts because of performance issues but if bearingTo is not the case I think it should have one.

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.
That's just a bug. Please file a ticket.
If so, could a different icon (say yellow menu instead of a white one) be used
for such slots?
Maybe, maybe not. Having a lot of different icons might be confusing, too?
