This is fixed in Pharo4 (I think we did that in Pharo3 already):

I should search the issue in the issue tracker… it seems to be Pharo4, so just 
1296 closed issues to check there…
I will search for it.

Another question: In the code I saw. ReadOnlyVariableBinding. I removed that in 
Pharo relatively early as it was not used:
half of the classes were stored that binding (old ones) all newer ones where 
just associations.
The code to make a binding "read only" was never called.

Is this now used in Squeak? Is it worth the complexity?

Squeak doesn't use ReadOnlyVariableBinding anymore. The bindings of classes are instances of the ClassBinding class. Without using separate class it's a bit cumbersome (and less OO) to decide if an assignment to a global variable should be allowed or not. E.g.:

        Foo := 1.

should work if Foo is a global, but not a behavior. It should raise an error if it's a behavior.
