I don't really know enough about the system to judge whether the
compiler is being over-conservative in this case.
A minimal case to reproduce the same error is:
Smalltalk at: #Foo put: #Foo.
Then define a class:
Object subclass: #FooTest
instanceVariableNames: ''
classVariableNames: 'Foo' "This is the trigger"
poolDictionaries: ''
category: 'ClassVar-Testing'
On save, a debug window with "DuplicatedVariableError: Foo is defined
elsewhere" is shown.
I've tried this with a selection of images in the 1.4 set from
14400-14414 and with 1.3 13315 with the same results. It seems that
Class>>declare: calls Class>>bindingOf: to check if a symbol is
already bound, and this always returns non-nil for globals.
