Bernhard,

This looks like a bug. It is not an error in Smalltalk in general to have a
class variable with the same name as a global. Other dialects allow this
without any problem.

Squeak has an additional problem in that class variables aren't always
looked up correctly when inherited. I posted about these issues and supplied
a fix for 3.6, with tests, a few months ago.

But there was some discussion about whether it should be allowed in the
first place to have class variables shadow globals with the same name. I
personally don't see how that could reasonably be avoided, plus it doesn't
cause any problems. In fact the nesting of shared variable enviroments helps
prevent unintended interactions between modules. I hope the powers that be
decide to fix this.

Cheers,

Peter
